3.3 Connecting the detector capillaries
The amperometric detector has a preheating capillary in its interior that
ensures that the eluent flows through the measuring cell at a constant
temperature.
Connecting the preheating capillary is optional. If the ambient conditions
are optimal or if the eluent in the column is heated, then the measuring
results can be sufficiently accurate, even without the use of the preheating
capillary.
Caution
The preheating capillary may not be used with readily flammable liq-
uids!
In the event of a leak, the fluid might evaporate and ignite in the heat-
ing area.
If the preheating capillary is used, proceed as follows:
Connecting capillaries to the measuring cell
1 Connect the preheating capillary
Note
This preheating capillary must be tested with the IC instrument the
first time the detector is put into operation, see Chapter "Start-up"
in the manual for the detector.
￭ Use a pressure screw (6.2744.014) to connect the detector input
capillary to the connector Eluent in on the detector.
￭ Use a pressure screw (6.2744.014) to fasten a piece of the PEEK
capillary (6.1831.010) to the Eluent to cell connector on the
detector.
2 Connect the cell input
Use a pressure screw (6.2744.014) to fasten the other end of the
PEEK capillary (6.1831.010) to the In connector on the measuring
cell.
