Arsenometer HMAS100 

Instruction Manual v2.0

 

 

 

 

2.3. OPERATING PROCEDURE

 

2.3.1. METHODS

 

 

The Arsenometer operating procedure consists of two main steps 

– plating 

(conditioning) and analysis. The plating step forms a plate on the surface of the 
working electrode which can be seen as a yellow/gold layer on the tip of the Working 
Electrode. The quality of this plate is essential to achieving reliable

 

results.
