Mobile Phase Cleaner for UHPLC/HPLC

GLC Suction Filter 2

HPLC Suction filter with mobile phase cleaning function

Features
Removes contaminants from the mobile phase.
Does not affect gradient delay* to install this product in front o fthe pump (see Fig. 2).
Available for LCMS due to low bleed.

(*The delay form the time a gradient begins to be produced in the pump to when it
reaches the column inlet).

Flow
The GLC Suction Filter 2 is packed with activated GLC Suction Filter 2
carbon which acts as a chemcal trap and removes Column
contaminants present in the mobile phase.
This product is easy to install and user-replaceable.

Removal of contaminants in mobile phase (LC/UV)

e.g. Removal of contaminants caused due to the storage of the mobile phase

Ghost peaks are contaminant peaks that appear even when no sample is injected. One of the causes for ghost peaks is contamination
in mobile phase due to improper storage or from external sources. We prepared contaminated ultrapure water that was stored in
a plastic container (polyethylene) at room temperature for two weeks. Ghost peaks were observed when using the contaminated
water as mobile phase. After installing the GLC Suction Filter 2, the previously observed ghost peaks were eliminated.
