5. OPERATING PROCEDURE
5.1. Methods
The Metalyser
®
operating procedure consists of three main steps – Plating
(Conditioning), Analysis and Results. The plating step forms a plate on the
surface of the working electrode which can be seen as either a grey or
yellow/gold layer on the tip of the Working Electrode. The quality of this
plate is essential to achieving reliable results.
The following table illustrates which electrode to use for each element:

If WE1 is to be used in the analysis, then WE2 is not part of the circuit and
has no role in the analysis. Likewise for WE1 during analyses using WE2.
When switching between different analyses, the unused electrode needs to
be removed, otherwise results may be affected.
Procedures for each parameter are detailed in the relevant application
notes.
