40 1100 Series Capillary LC System Manual

2 Optimizing Performance

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 gradient response.

• The detector is used at medium or low sensitivity.

The standard filter

The standard filter has a volume of typically 100 µl. If the application needs a

reduced volume (e.g. for fast gradient) the 20 µl low volume filter

(01090-68703) is recommended. Be aware that the filter efficiency and

capacity is significantly reduced compared to the standard one.

NOTE

Removing the mixer will result in an increase of the composition wander and higher

detector noise.

NOTE

Never run the capillary pump without an inline filter.
