51 Maintenance and Care

Checking the Fittings

Check if all fittings are tight. If fittings are not tight, re-tighten
fittings.
Capillary fittings
Stainless steel fittings
PEEK fittings

Putting the Device out of Operation

The detector is designed for use with different solvents. If the
detector is out of operation for several weeks, residual solvent
can cause damage. Therefore, it is recommended to:

flush the flow cell, the capillary, and the detector

remove the used solvent completely

fill the flow cell, the capillary, and the detector with isopropa-
nol
Seal the open connectors of the flow cell with cap fittings.
Prerequisite The detector head has been purged.
Tools Cap fittings and/or screw-type cap fittings
Procedure Process
1. Remove the solvent tubing and seal all open connectors
with cap fittings.
2. Disconnect the detector from the HPLC flow system and
seal the open connectors of the flow cell with cap fittings.
Next steps Choose a storage location according to the ambient conditions
listed in the respective chapter of this user manual.

Storage

Note that prior to storing all tubes and capillary should be emp-
tied or filled with an appropriate flushing solution (e.g. isopro-
panol). To prevent algae formation, do not use pure water. Seal
all inlets and outlets with cap fittings.
Note the ambient conditions for storage (See "Ambient condi-
tions" on page 58, 59, 60).
