Instructions for nitrite ion electrod

1.1 Introduction

The nitrate ion selective electrode developed by our company is mainly composed of a working electrode made of polyvinyl chloride and ion active materials and a built-in reference electrode. The electrode is designed to measure nitrate ions (NO2-) in aqueous solutions. It is suitable for the rapid determination of the concentration of nitrate ions outdoors and in the laboratory. It has the characteristics of rapid measurement, accuracy, and easy operation.

1.2 Basic instrument and solution requirements

(1) Nitrate ion selective electrode
(2) Ion analyzer or millivolt meter
(3) Standard solution: 1000ppm NO2-standard solution
(4) ISA (ion buffer)1.3 Main parameters
