## .. 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.
