    The invention relates to a measuring technique and can be used for electron-optical aided sampling. Devices for electron-optical identification of samples are known, comprising a light source, a photodetector, and sample stores. recording device. In this device, the test sample is introduced into a cuvette, which is made of a light-transparent material l. However, the known technical solution for all positive recognizers of the device requires extremely high technical costs. Subjective errors of measurement results arise. In addition, for each measurement it is necessary to carry out the designation of the cuvette, and each cuvette can be applied only once. The closest to the technical essence of this invention is a device for electron-optical identification of samples, containing optically coupled pulsed light source, a photoreceiver and stores with samples, as well as a recorder, a transporting device, an indicator unit, the input to which is connected to a photoacceptor, an output - with a registrar 2. The disadvantage of this device is low reliability in the identification of samples. The purpose of the invention is to increase the Total and reliability of the control of samples. This goal is achieved in that a device / containing an optically coupled pulsed light source, a photodetector and sample shops, as well as a recorder, a transporting device, an indicator unit, whose input is connected to a photodetector, and an output with a recorder, is entered into a pedometer, shops with the samples are equipped with light switches made in the form of a binary code, and the photodetector is made in the form of a matrix, the number of elements of which is equal to the number of digits of the binary code, and the space between the photoreceiver and the source veto configured as a channel to store a sample passageway pedometer input coupled to the conveying device and the pulsed light source, and outputs the pedometer coupled to the input and display unit, .registratora. Light switches are located in a row under sample openings of sample stores and are made in the form of holes or slots or recesses, and the walls of the recesses are lined with a reflective layer, while the light source is made in the form of a fluorescent lamp, and the photodetector and light source are located along both sides of the study area or on one side of the study area. Figure 1 shows the input part of the device for electron-optical identification of samples with the main nodes; 2 shows a magazine for receiving samples or receptacles with samples. Stores 2 are inserted into the inlet feed chamber 1 of the device 1. The clamping device 3 ensures the preloading of the magazine 2. With the aid of the transport device 4, the stores 2 move intermittently through the probing zone 5 to the exit chamber b. Unit 7 feed provides transportation stores in the direction of the output chamber.
    The probing zone 5 is made in the form of Kayal, located between the source 8 of the light and the system (matrix) of 9 radiation detectors. The light source 8 is made in the form of a rod fluorescent lamp, and the system 9 of radiation detectors is in the form of a set of photodiodes. The transport device 4 is connected with the pedometer 10, the signal from which, together with the signal from the matrix (9 radiation detectors, acts on the indicator unit 11. The indicator. Unit 11 outputs the sample data in digital form and controls the printing (recording) device 12 which through the second input 13 receives the result of the analysis related to this sample.
    Store 2 (FIG. 2) is in the form of a rectangular block and contains ten receiving ports 14 for samples or sample vessels. Each hole 14 is equipped with a digit from well to nine, and each store 2 is provided with a numerical designation 15, so that the position of the hole 14 with its position number and the designation 15 of store 2 characterizes the corresponding sample.
    On the bottom side of the magazines 2 holes or grooves or recesses-grooves 16 are used, which are used as a light switch with a binary code.
    The device works as follows.
    Before starting work, the corresponding number of stores 2 is entered into the input feed chamber 1. With the device start-up indicator. chain 11 sets pedometer 10 to the zero position. At the zero position of the pedometer 10, the lammer fires - the light from which illuminates all the photodiodes of the matrix, since at this moment
    in zone 5 there are no shops 2. At this moment the indicator circuit 1 does not measure. The transport device starts at the same time as the flash lamp is started. And intermittently moves the lower magazine 2 in the direction indicated by the arrow. In addition, each step is recorded by the pedometer 10. Since the pedometer operates on a decimal basis,
    0 and the spatial location of the probe zone 5 is made so that after ten steps the store 2 is exactly in the probe zone, at the moment when the pedometer 10 passes
    5 a path from nine to zero, a repeated light flash occurs, Light through the light switch 16, which provides the corresponding coding of store 2, hits the photodiodes, and the digits 15 are captured by the dicker circuit 11; During further transportation, the process is repeated.
    The measured values are fixed at the input of the printing unit 2, which is synchronized by the operating transport device in such a way as to guarantee on the printing device 12 an exact correspondence of the measured values with sample designations.
    iIf store 2 leaves probing zone 5, then feed unit 7 displaces it to output chamber 6,.
    5 and the space in this zone is freed up for the next store 2. After the last store has been transported 2 steps through the probe zone 5, the light pulse is off.
    0 falls on all photodiodes, and then the process repeats.
     In this way, reliable control of sample accessory is ensured.
