Caution
For the capillary connections between the injection valve (see Chapter
2.14, page 40) and detector (see Chapter 2.19, page 57), 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.
