3.3 Conductivity detector
3.3.1 Connect the detector capillaries
Connecting the detector output capillary
To connect the detector output capillary, you will need the following
accessories:
￭ PEEK capillary (6.1831.030)
￭ Pressure screw (6.2744.010)
1 Use a pressure screw (6.2744.010) to screw one end of the PEEK
capillary (6.1831.030) firmly to the coupling Cond. Eluent out.
2 ￭ Guide the other end of the PEEK capillary (6.1381.030) into a suf-
ficiently large waste container and fasten it there.
OR if the application requires a subsequent amperometric detec-
tion:
￭ Connect the other end of the PEEK capillary (6.1381.030) to the
Eluent in connector on the amperometric detector.
Note
The detector output capillary must be free of blockages in order to
generate sufficient backpressure (the measuring cell is tested to 5
MPa = 50 bar backpressure).
Connecting the detector input capillary
Depending on the equipment of the IC instruments the detector input
capillary is connected differently:
￭ With instruments without suppression, directly to the separation col-
umn (see "Connecting the detector input capillary to the separation
column", page 16).
￭ With instruments with chemical suppression, to the suppressor (see
"Connecting the detector input capillary to the suppressor", page
16).
￭ With instruments with sequential suppression, to the MCS (see "Con-
necting the detector input capillary to the MCS", page 17).
