761 Compact IC

2.3.6

Filter unit PEEK

One 6.2821.120 Filter unit PEEK (see Fig. 8) is already installed be-

tween the high-pressure pump and the injection valve at the 761 Com-

pact IC. This filter unit serves to avoid contamination by abrasive parti-

cles of the piston seals.
The two other filter units PEEK supplied with the 2.761.0020 Compact

IC (with suppressor) are installed between the pump tubings of the

peristaltic pump and the inlet capillaries for regeneration and rinsing so-

lution (see section 2.8.2). These filter units serve to protect the suppres-

sor module from foreign particles and bacterial growth.
The Filter unit PEEK 36 consists of the filter-housing 59, the filter-screw

57 and the 6.2821.130 filter 58. For the connection of capillaries 56

PEEK compression fittings 54 (6.2744.010 or 6.2744.070) must be

used. New filters 58 are available as an option with the ordering number

6.2821.130 (set of 10).

For the connection of the filter unit, please note the flow direction

arrow printed on the housing.
