Caution
For the capillary connections between the injection valve and detector ,
PEEK capillaries with an internal diameter of 0.25 mm must be used.
These are already connected to a newly delivered instrument.
PTFE capillaries (poly-
tetrafluoroethylene) PTFE capillaries are transparent and enable visual tracing of the liquids to
be pumped. They are chemically inert, flexible and temperature-resistant
up to 80°C.
Usage:
PTFE capillaries (6.1803.0x0) are used for the low pressure range.
￭ PTFE capillaries with internal diameter of 0.5 mm for sample handling.
￭ PTFE capillaries with internal diameter of 0.97 mm for the sample han-
dling as for rinsing and regeneration solutions (they do not have to be
in the scope of delivery of the instrument).
Note
Capillaries must have a flawless level cut edge. For cutting PEEK capilla-
ries only use the 6.2621.080 capillary cutter.
