5. OPERATING PROCEDURE
5.1. METHODS
The Metalyser
®
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
either
a
grey
or yellow/gold
layer
on the tip of the
electrode. The
quality
of this plate is
essential
to
achieving
reliable
results
and
therefore
a
secondary
conditioning
step is
included.
The following
table
illustrates
which electrode to use for each element:

Black (no plating required)
*Not available as standard
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.
