Actual primary flow values may vary from system to system. In any case the standard
configuration is changed, the primary flow could be higher compared to the values in
above table.

Static Mixer and Filter

The capillary pump is equipped with a static mixer and an inline filter in front of the
EMPV.
The standard static mixer
The standard static mixer has a volume of typically 420 µl. To reduce the delay volume
of the capillary pump you can remove the mixer.
Conditions to remove the static mixer:
• The delay volume of the capillary pump should be reduced to a minimum for fastest
• The detector is used at medium or low sensitivity.
NOTE
Removing the mixer will result in an increase of the composition wander and higher
detector noise.
