## .. ØPURGE .....
Function
Switch off purging.
Description
The
ØPURGE
instruction is used to switch off the inert gas purging for the
measuring vessel on the 747 VA stand switched on with
PURGE
. Purging
is used to remove the electrochemically active and hence interfering
oxygen in aqueous solutions. With the inert gas flow rate of ca. 20 L/h set
on the 747 VA Stand, a purging time of ca. 3...5 min usually suffices.
Comment
If the purging should be switched off automatically after a definite time,
the
TPURGE
instruction can also be used.
