6.2744.010 PEEK compression fittings can be used. The flow direction
is arbitrary. The pulsation dampener is positioned in the interior of the
820 IC Separation Center on the base below the injection valve (see
819/820 Instructions for Use).
The pulsation dampener is filled with isopropanol when new. Rinse
your IC system carefully after the first installation of a new pulsation
dampener.
2.3.3 Filter unit PEEK
The 6.2821.120 Filter unit PEEK 24 supplied (see Fig. 4) 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 21, the filter 22 and the connector 23 to be
screwed into the housing 21. For the connection of capillaries 19, PEEK
compression fittings 20 (6.2744.010) must be used.
New filter 22 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
arrow 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.
