Purging Procedure
Purging Procedure
1
Ensure that an outlet tube is connected from the purge valve to a waste
solvent bottle.
2
Open the purge valve.
3
Enter the
Analysis
screen.
4
Set the purge flow rate in the regular flow rate section of the
Analysis
screen, for example, to 5 ml/min.
5
Set the first channel to be purged to 100%. We recommend you start with
the organic solvent channel first. Channel A will automatically be set to
100% when all other channels are set to zero or OFF.
6
Turn on the pump using the
On/Off
button [
F7
] in the
Analysis
screen.
7
Wait until a continuous stream of solvent comes out of the outlet tube from
the purge valve.
8
Turn off the pump using the
On/Off
button [
F7
] in the
Analysis
screen and
then close the purge valve.
9
Repeat the procedure for the other channels you need to purge.
N O T E
If a flow rate of more than 5 ml/min is used on a quaternary pump, redefine the upper
pressure limit to 200 bar (Accessible from the Analysis screen, press the Settings button
[F1], choose pump from the list and press the Enter key. Then choose More ...)
N O T E
The channels of a pumping system are named A, B, C and D (depending on the pump type).
%A is automatically calculated by 100% - (%B + %C + %D). If no values for %B, %C and %D
are entered, %A is always 100%. To purge the pump you have to go through steps
to
individually for each of the channels, setting the composition to 100% for the
channel to be purged.
