4.6.2 Purging the Pump By Using the Autosampler
2
If the UltiMate 3000 system includes a WPS-3000RS or WPS-3000SL autosampler, you
can purge the pump also from Chromeleon via the membrane pump of the autosampler. In
this way, you can remove small amounts of air, for example, after exchanging the solvent.
To achieve optimum results, purging should be performed with a flow rate as high as
possible (recommended: 3 mL/min for SD and RS pumps; 2 mL/min for BM pumps).
In addition, the static mixer or inline filter, depending on the pump type, should be permeable.
Check the permeability (

page 148 for the static mixer or page 152 for the inline filter).
1. Open the Properties dialog for the pump in the Chromeleon Server Configuration
program (

page 42).
2. On the Devices page, check the entry in the WPS Purge Port box to find out whether
and with which autosampler the pump is fluidically connected (

page 38).
3. In Chromeleon, open the Commands dialog box for the pump (

page 65) and check
and change the PurgeViaSampler setting if necessary:
Property Setting
PurgeViaSampler
Select Yes to purge the pump by using the autosampler when Purge = On .
The property is listed under PumpModule > [Pump Device Name] (

page 37).
4. Start the purge cycle. To do so, set Purge to On .
This is what happens: The autosampler needle descends into the wash port, and the
solvent is drawn and directed to the waste through the membrane pump of the
autosampler. The purge cycle is performed with the time and flow rate settings made
under PurgeTime and PurgeFlow (

page 54).
When the specified PurgeTime has elapsed, Purge is automatically reset to Off. You can
stop purging also manually by setting
Purge to Off .
