nectors supplied or two 6.2744.010 PEEK compression fittings can be
used. The flow direction is arbitrary. The pulsation dampener is posi-
tioned in the interior of the 820 IC Separation Center on the base below
the injection valve (see Fig. 21, Fig. 22, Fig. 23, resp. Fig. 25).
The pulsation dampener is filled with isopropanol when new. Rinse
your IC system carefully after the first installation of a new pulsation
dampener.
2.7.3 Filter unit PEEK
The 6.2821.120 Filter unit PEEK 47 supplied (see Fig. 18) serves to
avoid contamination of the piston seals by abrasive particles and can
be used in the pressure range 0 … 30 MPa (0 … 300 bar). The filter unit
consists of the housing 44, the filter 45 and the connector 46 to be
screwed into the housing 44. For the connection of capillaries 42, PEEK
compression fittings 43 (6.2744.010) must be used.
New filter 45 are available as an option with the ordering number
6.2821.110 (10 pieces).
For the connection of the filter unit, please note the flow direction ar-
row printed on the housing.
The filter unit is filled with isopropanol when new. Rinse your IC system
carefully after the first installation of a new filter unit.
