    Step to analyze a sample
    CH 711 779 B1
    Description Field of the Invention The present invention relates to a method for automatic real-time analysis of an organic contaminant using a real-time solid-phase micro-extraction GC or solid-phase micro-extraction GC / MS analysis system, by means of which the real-time, constant taking of a sample also using an existing analysis device a generation time of a high concentration of a harmful, organic pollutant can be recognized quickly and precisely and a suitable countermeasure can be taken in a water treatment plant, etc.
    PRIOR ART Due to industrialization and urbanization, environmental pollution has long emerged as social problems, while at the same time the systematic monitoring of drinking water quality, e.g. Protection of the drinking water supply source, administration and regulation of the plants for the discharge of the pollutants etc., become strict within the national framework. A basis for these controls is a quick and accurate measurement of the contaminants in the water. Since a quick water quality measurement in the drinking water supply sources associated with drinking water, purified water and tap water, etc. can enable a quick water purification process, it is even more important in view of safety.
    Organic contaminants managed by the water supply system include dozens of types of substances, such as volatile organic compounds, agrochemicals, disinfection by-products as well as tasting and malodorous substances, etc. Since these organic pollutants have harmful effects on human health or have a direct effect on the quality of tap water by causing an aesthetic problem, it is necessary to fill such pollutants fully and to manage entirely. Recently, the tasting and malodorous substances (geosmin, 2-MIB (methylisoborneol)) are increasingly being increased by the pollutants of this type in their concentration and production frequency flowing into the water treatment plant, because the algal bloom due to climate changes, e.g. Rises in water temperature and changes in rainfall patterns, etc., are caused more and more. Therefore, by using a water purification material such as e.g. powdery activated carbon, etc., in the water treatment plant and thus by taking quick countermeasures to less than an odor threshold before they can flow into a water supply network, so that customer complaints can be avoided. This requires more complete administration.
    In the current water treatment plants, the tasting and malodorous substances are analyzed in the normal state once or less per day and only when the high concentration of the same occurs twice a day, but it is currently not easy to measure a constantly changing water quality manually and thus take a countermeasure to the rapid water purification process. It is necessary to add in real time the volatile organic compounds and agrochemicals, both of which arise in emergency situations, such as leak accidents in chemical plants, roll-over accidents of tankers transporting the chemicals, in the water supply network, as well as the disinfection by-products, which only arise in small quantities during the water purification process monitor, but only manual measurement can take place, which is why it is difficult to combat such contaminants by rapid detection.
    In order to solve these problems, efforts have so far been made to monitor the water quality in real time.
    For example, various technologies for real-time monitoring of water quality have been proposed by the following South Korean registration patents:
    Registration Patent no. KR 10-0 901 779 (2.6.2009) with the title “Internet-based monitoring and control system for measuring water quality”, registration patent no. KR 10-0 522 764 (12.10.2005) with the designation "Device for real-time monitoring of water quality and method for controlling the same", registration patent no. KR 10-1 406 884 (5.6.2014) with the title "Multi-wavelength analysis-based online system for measuring water quality for the real-time detection of organic contaminants in water", and registration patent no. KR 10-1 253 251 (4.4.2013) with the designation "Device and method for real-time monitoring and control of substances that cause taste and smell for the purpose of water purification".
    But most of the above prior art patents relate to the measurement of the basic parameters of water quality (e.g. water temperature, pH, turbidity, electrical conductivity of a residual chlorine, etc.) or of the total index parameters of organic materials (e.g. total organic carbon (TOC), chemical oxygen demand (COD), etc.), some of which relate to the method for real-time measurement of certain organic contaminants. In these patents, however, methods are used which are different from existing analysis devices or by combining the different expensive equipment with one another, which consequently leads to the disadvantage that accuracy, reliability and economy are reduced and operation and administration are made more difficult.
    CH 711 779 B1 As mentioned above, the organic pollutants in the water, e.g. tasting and malodorous substances etc., furthermore are analyzed even more frequently. However, the registration patents describe the combination of the separate expensive equipment with one another, which is why this is uneconomical and can only be operated and managed in a complicated manner. As a widespread device for analyzing an organic pollutant in water, an analysis device consisting of a solid-phase microextraction device and a gas chromatography mass spectrometry analysis device is currently used extensively, but the degree of utilization of this analysis device is too low and so new devices have to be rebuilt, which is consequently inconvenient Leads to problems.
    DISCLOSURE OF THE INVENTION Object of the Invention The object of the present invention is to solve the problems and / or disadvantages summarized above and found in the known technologies.
    With the present patent application, an arrangement for the automatic real-time analysis of an organic pollutant in water is described, by means of which a practical analysis system is developed by automating all measurement processes of the respective sizes of the organic pollutant in the water using an analysis device that has been widely used for manual analysis which enables measurement results to be used to manage water quality quickly in real time, certain organic pollutants, such as tasting and malodorous substances, volatile organic compounds, agrochemicals and disinfection by-products etc., to be analyzed in real time, measuring these contaminants in a controllable degree of concentration (several ng / L levels in the case of the tasting and malodorous substances) as well as reliable measured values, economical maintenance and easy to assemble and operate.

    In addition, in this advantageous embodiment, as can be seen in FIGS. 2 to 5, it is provided that a heating block 20 between the solid-phase microextraction device 11 and the gas chromatography-mass spectrometry analysis device 12 of the above analysis device 10, in particular on the top of the gas chromatography -Mass spectrometry analysis device 12 is arranged, wherein a plurality of sample bottle seat recesses 21 are formed on an inside of the heating block and wherein the heating block itself is provided in its entirety with a heating means 22 and temperature sensor 23 for heating.
    It can be provided in this embodiment that the plurality of sample bottle seat recesses 21 are arranged at a certain distance from one another and that a magnetic or oscillating stirring means 24 is additionally enclosed within the heating block 20.
    In addition, in this embodiment, as can be seen in FIGS. 2 to 5, it is provided that a sample bottle 30 can rest against the sample bottle seat recesses 21 formed in the above heating block 20, with a receptacle 31 for receiving on an inside of the sample bottle a sample to be used for checking the water quality is designed so that the sample received by the receptacle 31 is absorbed by the solid-phase microextraction device 11 of the above-mentioned analysis device 10.
    It is advantageously provided that the receptacle 31 of the above sample bottle 30 is so large in capacity that it can accommodate a quantity between 100 and 150 ml, but this is not particularly limited.
    Of course, a plug (not shown in the figure) is formed on an upper side of the sample bottle 30, which plug can close the sample bottle and through which the needle of the syringe can pass.
    In the sample bottle 30 are also a sample feed 32, which serves to feed the sample 31 to the sample, and a sample discharge 33, which serves to remove the sample received in the receptacle 31 after the sample for analysis from the Analyzer 10 was removed (concentrated / extracted).
    It is advantageously provided that the sample feed 32 is formed at the upper end of a side surface of the sample bottle 30, but this is not particularly limited, wherein it is also advantageously provided that the sample discharge 33 for easy removal of the sample at the bottom End of the side surface of the sample bottle 30 is formed.
    In addition, in this advantageous embodiment, it is provided that a sample supply and removal unit 40 is connected to the sample bottle 30 and thus can supply and remove the sample.
    It is provided, as can be seen in FIG. 3, that a sample feed line 42 is constructed in the sample feed and removal unit 40, which is connected to the sample feed 32 of the sample bottle 30, with a sample feed line 42 in this sample feed line 42. Control valve 42a is constructed, by means of which the sample can be supplied or blocked.
    That is, it is designed such that one end of the sample supply line 42 is connected to the sample bottle 30, while another end thereof is connected to a line of a medium that an analyst wishes to analyze, i.e. of an object that the analyst wants to check for its water quality, e.g. Raw water (from water, lake, etc.), processed water in the water treatment system, treated water, etc. is connected, so that the sample can be provided in real time to the receptacle 31 formed in the sample bottle 30.
    In this case, in a section which is connected to a position of the sample supply line 42 in which the analyst wants to check the water quality, a pump 42b can additionally be arranged, which can convey the fluid (the sample). In addition, a washing line (not shown in the figure) is additionally arranged at the end of the sample supply line, which can supply a washing water for washing the interior of the sample bottle 30, or the end is connected to a section to which the washing water is supplied, so that this washing water can be fed to the sample bottle.
    In contrast, it is designed such that a water discharge line 50 is connected to the above sample supply line 42, so that new sample can always be provided to the sample supply line.
    Here, the water discharge line 50 is formed such that it branches off from the sample supply line 42, i.e. that it is between a position in which the water quality should be checked and that in the
    CH 711 779 B1
    Sample supply line 42 arranged sample supply control valve 42a is arranged, but it is even more advantageous that it is arranged directly upstream of the sample supply control valve 42a.
    In contrast, it is provided in this advantageous embodiment of the invention that a component is provided to enable the quantitative analysis, which can be filled with a certain amount of the sample bottle 30 to be supplied to the sample.
    For this purpose, the sample bottle 30 has a sample supply amount control unit 34, which is designed to be able to receive the specific amount of sample by means of the receptacle 31, the sample supply amount control unit 34 being arranged on a side surface of the sample bottle 30. However, it is advantageously provided that the sample supply quantity control unit is arranged at an exact height at which the receptacle 31 can be completely filled with the sample, so that only the specific quantity of sample can be accommodated in the receptacle 31.
    Furthermore, it can additionally be provided that a sample supply quantity control line 60 has a sample supply quantity control valve 61, which connects the sample supply quantity control line with the sample supply quantity control unit 34 formed in the sample bottle 30.
    It can advantageously be provided that the above-mentioned valves are designed to be electronically controlled, similar to an electromagnetic valve, so that they can be opened or closed by the control of a control unit C.
    The analysis method according to the invention is described in more detail below, which can be carried out by means of the real-time solid-phase microextraction GC or solid-phase microextraction GC / MS analysis system 100, which has the structure mentioned above.
    1. Step for providing a sample First, the real-time solid-phase micro-extraction GC or solid-phase micro-extraction GC / MS analysis system 100 is the one that can analyze the organic pollutants in the water automatically in real time using the analysis device 10 that has been used previously , and must be set up in locations or laboratories etc. within the corresponding water quality test zones in order to use the test water, e.g. treated water, raw water and processed water, which are processed in a water treatment plant, e.g. Water treatment plant, arises to check its water quality.
    Thereafter, the test water is provided in real time via the sample supply line 42, which is formed in the sample supply and removal unit 40 and is connected to the sample supply 32 of the sample bottle 30.
    The supply process by means of which the test water is supplied to the sample bottle 30 via the sample supply line 42 takes place in such a way that the conventional control unit C opens the sample supply control valve 42a arranged in the sample supply line 42 so that the test water can be made available to the sample bottle, 5, while a sample discharge control valve 43a of a sample discharge line 43 which is arranged in the sample supply and discharge unit 40 connected to the sample discharge 33 of the sample bottle 30, and a water discharge control valve 51 of a water discharge line connected to the sample supply line 42 50 are controlled in a closed state, so that the receptacle 31 of the sample bottle 30 is filled with the sample as the test water.
    It is possible that the sample provided via the sample feed line 42 is provided by means of a conventional pump 42a or is moved by a water pressure arising from the purified water or raw water.
    In this way, does the amount of sample filled in the sample bottle 30 reach a certain quantity, i.e. a position on which the sample supply quantity control unit 34 of the sample bottle 30 is formed, then the excessive sample supply quantity control line 60 provided via the sample supply quantity control unit 34 is discharged to the outside, so that only the specific quantity of sample in the receptacle 31 is filled.
    2. Step for analyzing a sample If the determined quantity of sample is filled in the above-mentioned manner, the sample supply control valve 42a arranged in the sample supply line 42 and the sample supply quantity control valve 61 arranged in the sample supply quantity control line 60 are controlled by the control unit C closed and thus the receptacle 31 inside the sample bottle 30 is separated from the outside, as can be seen in FIG. 7, so that a sampling (concentration extraction) can be carried out by the analysis device 10 and an analysis work can be carried out, while the sample which is continuously provided via the sample feed line 42 can be carried out by the Opening the water discharge control valve 51 of the water discharge line 50 can be discharged via this water discharge line 50.
    An effect can be achieved by means of the water discharge line 50 that the sample existing in the sample supply line 42 can only be left over by the quantity to be provided in real time.
    CH 711 779 B1 [0050] That is, the object of the invention was to identify, by analyzing the sample supplied in real time, the point in time at which the organic contaminants are superfluous within the sample, as explained above. Therefore, the above water discharge pipe 50 has been introduced, whereby it acts in such a way that the sample existing in the sample supply pipe 42 is maintained only by the quantity to be provided in real time and thus can be analyzed in real time.
    Thereafter, a needle of the solid phase micro extraction device 11 for concentrating / extracting the sample is positioned in a head space within the sample bottle 30.
    In contrast, the heating block 20 receiving the above sample bottle 30 is heated to the temperature suitable for the analysis (regulated according to the analysis size) and, if necessary, the stirring means 24 is operated so that the organic contaminants removed from the receptacle 31 of the sample bottle 30 Can move sample well into the head space within the sample bottle 30.
    Thereafter, the solid phase microextraction device 11 of the analysis device 10 is operated and thus absorbs the sample of the sample bottle 30, so that this sample is then inserted into the gas chromatography mass spectrometry analysis device 12 and thus the analysis work of the same is carried out.
    During the process in which the work is performed by the analyzer 10, the constant supply of the sample to the sample bottle 30 is of course carried out by means of the components as mentioned above. If the analysis work is completed by the analysis device 10, then the sample received in the other sample bottle 30 can then be analyzed in succession.
    In contrast, the sample of the sample bottle 30, from which the analyzer 10 has taken the sample to be analyzed, by opening the sample discharge control valve 43a of the sample discharge line 43, which is connected to the sample discharge 33 formed in the sample bottle 30, and the The sample supply quantity control valve 61 of the sample supply quantity control line 60 is discharged to the outside, as can be seen in FIG. 8, the new sample then being made available again via the sample supply line 42, and the sample remaining in the receptacle 31 of the sample bottle 30 is thus discharged via the sample discharge line 43 , so that thereafter, in a state in which the sample discharge control valve 43a is closed, the sample supply amount control valve 61 of the sample supply amount control line 60 is closed. In this way, the procedures for taking up and analyzing the sample can therefore be carried out repeatedly.
    Since the sample provided via the sample supply line 42 of the sample supply and removal unit 40 represents the one that is provided in real time, the real-time sampling and the sample analysis are carried out by the analysis device 10 in succession, so that an increase in the concentration of the organic pollutants occurs quickly recognized and constant analysis can be made possible.
    In contrast, a plurality of sample bottles 30 can be formed on the heating block 20. Only the sample can be taken from any position, however, the one sample supply and removal unit 40 connected to any sample bottle 30 is arranged in the processed water, while the other sample supply and removal unit 40 connected to the other sample bottle 30 is arranged in the raw water is arranged, etc., so that the sample analysis can be carried out simultaneously by the analyzer in different positions.
    In addition, it is designed according to the invention in such a way that the above sample bottle 30 is designed in terms of its capacity in a size between approximately 100 and 150 ml, so that a sufficient amount of organic contaminants can be included therein, the temperature being maintained by the heating means 22 and the temperature sensor 23 of the heating block 20 and the extraction (concentration / extraction) of the sample can be carried out effectively by the stirring means 24, which consequently also leads to an advantage that a sufficient degree of analysis sensitivity during the analysis of the sample by the analysis device 10 without operation Inserting the separate reaction chemicals can be obtained.
    In particular, if the analysis of the sample represents a process for automatic real-time analysis of the tasting and malodorous substances of the sample, then the arrangement according to the invention has the advantage that, in addition to the chemical analysis by the analysis device 10, a sensory analysis work can also be carried out in parallel which the human being actually smells at the sample and thus analyzes.
    As mentioned above, it can be provided that the existing equipment is used unchanged by installing the separate equipment in the analyzer, the sample being continuously provided in real time and thus a point in time at which an event occurs is quickly recognized, so that a quick countermeasure can be taken, and at the same time the present invention can easily be applied to the existing analyzer 10, so that it is not necessary to introduce new equipment, which consequently can lead to an economically very useful effect.
    It should be noted that the above-mentioned embodiments describe only one advantageous embodiment, the present invention can be changed and carried out in various forms.
