专利说明:

The invention relates to the field of analytical chemistry and can be used in potentiometric methods for the analysis of aqueous solutions.
The aim of the invention is to accelerate the determination of the concentration of ions in solutions.
The drawing shows a diagram of the device.
The integral sensor element 1 is composed of sensitive parts of ion-selective electrodes 2-4, made in the form of capillaries made of ion-sensitive glass. The sensing part 3 is connected by means of the analyzed sample 5 with the internal electrolyte of the reference Electrode 6.
The sensitive part 2 is connected by means of a reference solution containing a certain known amount of detectable ions, for example, a buffer in the case of a pH-sensitive sensor, with a reference electrode 7. Similarly, the sensitive part 4 is connected with another reference solution to the reference electrode 8. Sensitive parts 2-4 are placed in electrolyte 9, which provides galvanic communication between these parts.
The device works as follows.
The analyzed solution 5 enters the sensitive part of the integral .1 sensitive element 1, and the potential difference between
