Arsenometer HMAS100
Instruction Manual v2.0
2.3.2. PLATING
The plating step takes a few minutes.
There are two preliminary steps required for any analysis with the Arsenometer. The
plating step uses the AU500 Au Plating Solution and forms a plate on the working
electrode, covering the black tip with a yellow/ gold colour. The conditioning of the
electrode occurs when the element of interest is selected in the Test Methods menu
and then choosing condition electrode which is at the
top of the list when the element is
selected. The conditioning step should be carried out in sample water, and undertakes
a run which sensitises the Working Electrode.
