5.2.2 Initial electrode preparation
A new scTRACE Gold electrode needs to be initially activated and then
cleaned before it can be used for a determination.
NOTICE
The procedure Activation of the scTRACE Gold should only be carried
out once with a new electrode. Repeated activation will reduce the life-
time of the scTRACE Gold.
Activation of the scTRACE Gold
1 Load the example method AB416 Activation scTRACE Gold.detp
(see "Loading a method", page 23) .
2 Fill 18 mL cleaning solution into the measuring vessel (3- 3 ) . Use the
scaling on the vessel to measure the volume.
3 Position the measuring vessel on the base plate (3- 1 ) of the measur-
ing stand. Fit the measuring head, with scTRACE Gold, stirrer and
transparent ring assembled, in a way that electrode and stirrer
immerse into the solution. Press the measuring head down until the
stop.
4 Start the activation of the scTRACE Gold as described in Running a
determination (page 25) .
NOTICE
This method does not contain additions. The determination is fin-
ished after 4 replications.
5 When the activation is finished remove the measuring head, with
scTRACE Gold, stirrer and transparent ring assembled, empty the
measuring vessel and thoroughly rinse electrode, stirrer and vessel
with ultrapure water.
