Cyanide combination electrode hanna hi4109

Description

Cyanide combination electrode hanna hi4109 

The HI-4109 is a Cyanide combination ISE. It is ideal to be used for the determination of free Cyanide ions in plating baths, waste water and in plant and soil samples.

The HI-4109 cyanide selective electrode is a complete potentiometric cell that contains a silver/silver chloride (Ag/AgCl) reference housed within a PEI plastic body with a potassium nitrate electrolyte. The internal elements are isolated from the sample by a compressed silver halide sensing membrane.

Features

• Solid state sensor
  

• Skirted cone geometry
  

• Detection from 0.026 to 260 mg/L CN-

For the HI-4109 to measure cyanide accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the cyanide ionic strength adjuster (ISA) solution. The alkaline ISA ensures that the activity coefficient is constant so the concentration of free cyanide ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI-4109 cyanide solid state ISE can measure from 1µM (0.026 mg/L) to 0.01M (260 mg/L).
