Connection of PEEK capillaries
For the connections between high-pressure pump and detector block
6.1831.010 PEEK capillaries
(i.d. = 0.25 mm, e.d. =
1
/
16
"
) are used
which are connected using either
6.2744.010
PEEK compression fit-
tings
(long)
or
6.2744.070 PEEK compression fittings
(short)
.
These PEEK connectors can also be used to connect 6.1822.010 PTFE
microcapillaries (i.d. = 0.3 mm). Proceed as follows:
Capillaries fitted with new connectors must have a perfectly flat cut
surface. To cut PEEK or PTFE capillaries it is best to use the
6.2621.080 Capillary tubing cutter
.
