Operating Manual
1. Connect the capillary mixer to the static mixer.
Mind the direction of flow through the static mixer and capillary
mixer (indicated by the arrow on the mixer).
2. Insert the assembly of static mixer and capillary mixer into the
pump.
3. Insert the static mixer into the mounting bracket.
4. Connect the capillary mixer on the purge/sensor unit.
5. On the static mixer outlet, connect the capillary to the autosampler
injection valve.
6. In the Chromeleon software, set the StaticMixer property to the
value indicated on the static mixer. If the property is not set to the
correct value, the leak tests may not provide reliable results.
7. Apply the flow rate of your application and have the pump deliver
for a short time.
8. Inspect the flow connections on the mixer for indications of leakage
before resuming operation.
9. In the Chromeleon software, consider updating the Predictive
Performance information for the static mixer ( MixerChanged
command).
When operating the pump, observe the following
• Operating the pump with a mixing system with a volume lower than
the volume installed in the pump upon shipment reduces the
gradient delay volume but increases the ripple.
• Operating the pump with a mixing system with a volume higher than
the volume installed in the pump upon shipment reduces the ripple
but increases the gradient delay volume.
• The maintenance procedures are the same as for the mixing system
with which the pump was shipped (see
Mixing System (
