ISE - Ion Selective Electrode

ISEs are analytical tools widely used for potentiometric analysis of large scale of various ionic analytes, using various procedures of measurement and evaluation. These sensors are ecpecially suitable for routine analysis being done in agriculture and food process, soil analysis, environmental samples, water, pot-, waste-, boiler-, mineral-, and well water samples, tribotechnical analysis, explosives and pyrotechnical mixtures analysis, various applications in research laboratories, biochemical process controll, chemistry and other education laboratories, and many others.

Electrodes are applicable to all commonly used measuring apparatus, with internal resistance of above 109Ω, 1012Ω for gas sensing ones respectively. Standard electrical connecting element is 0,8 to 1 mt. coaxial cable with BNC connector. The other possible connectors are SMS, SN6, DIN, CINCH, banana, SN6 (or S7) head connector and appropriate connecting cable.

The work with ion selective electrodes is only a little time consumpting, requires an only small amount of chemicals, and a friendly price measuring equipment. O.d. 12 mm, cap o.d. 16 mm, length 145 mm. Standard electrical connecting element is 0,8 to 1 mt. low noice coaxial cable with BNC connector. Others, ”+” in type number, is as described by pH electrodes. Temperature range 0 – 40 °C, sodium 0 – 80 °C. Gas sensing, NH3 and CO2 electrodes are constructed as combined sensors. Combined electrodes, comb., are constructed as cell in one body, with reference electrode argentchloride, Ag/AgCl, KCl, c = 0,1 mol/l. They are for using in case, the polution of reference electrolyte, KCl, c = 0,1 mol/l, does not disturb the determination with ISE. The electric connection is like discussed in pH electrodes section.
