• Attach inlet capillary 90 90 using a 6.2744.010 Compression
fitting to the connector 55 55 of the filter unit PEEK (see section
2.6.3).
• Attach a piece of the 6.1803.020 PTFE tubing (from 752
accessories) cut to the required length using a 6.2744.010
Compression fitting to the connector 53 53 with filter at the other
end of the Filter unit PEEK.
• Attach the other end of the PTFE tubing using a 6.2744.010
Compression fitting to the 6.2744.030 Coupling (from 752 ac-
cessories) and mount it on the outlet end of the first length of
pump tubing.
• Mount a 6.2744.030 Coupling to the inlet end of the first
length of pump tubing. Attach a piece of the 6.1803.020 PTFE
tubing (aspirating tubing, from 752 accessories) cut to the
required length using a 6.2744.010 Compression fitting to the
other end of this coupling.
• Immerse the other end of the aspirating tubing in a vessel
containing regeneration solution (normally 20 mmol/L H

)
and fix in place.
• Pull outlet capillary 91 91 marked with "Waste" of the suppressor
module through the rear panel opening 43 43, lead it to a suffi-
ciently large waste container and fix it in place.

• Loosen rotary nipple screwed onto the interior side of con-
nection 28 28. Pull inlet capillary 93 93 marked with "H
2
O" (see
Fig. 17 and Fig. 18) by hand out of the opening of connection
28 28 as far as required. Retighten nipple on the interior side of
connection 28 28 to fix inlet capillary 93 93.
• Attach inlet capillary 93 93 using a 6.2744.010 Compression
fitting to the connector 55 55 of the filter unit PEEK (see section
2.6.3).
• Attach a piece of the 6.1803.020 PTFE tubing (from 752
accessories) cut to the required length using a 6.2744.010
Compression fitting to the connector 53 53 with filter at the other
end of the Filter unit PEEK.
• Attach the other end of the PTFE tubing using a 6.2744.010
Compression fitting to the 6.2744.030 Coupling (from 752 ac-
cessories) and mount it on the outlet end of the second
length of pump tubing.
• Mount a 6.2744.030 Coupling to the inlet end of the second
length of pump tubing. Attach a piece of the 6.1803.020 PTFE
tubing (aspirating tubing, from 752 accessories) cut to the
required length using a 6.2744.010 Compression fitting to the
other end of this coupling.
• Immerse the other end of the aspirating tubing in a vessel
containing rinsing solution (normally dist. H
2
O) and fix in
place.
• Pull outlet capillary 92 92 marked with "Waste" of the suppressor
module through the rear panel opening 43 43, lead it to a suffi-
ciently large waste container and fix it in place.
