6.2744.070 PEEK compression fitting (short). The connection pieces

are mounted on the capillaries as follows:

PEEK capillaries that are to be provided with new connection pieces

must have a perfectly flat cut surface. This is best achieved by using

the 6.2621.080 Capillary cutter available as an option.

1 Mounting the compression fitting

• At the end of capillary Fehler! Verweisquelle konnte nicht

gefunden werden. that is to be attached push either a

compression fitting Fehler! Verweisquelle konnte nicht

gefunden werden. (6.2744.010) or compression fitting Fehler!

Verweisquelle konnte nicht gefunden werden. (6.2744.070)

over the capillary as shown in Fehler! Verweisquelle konnte

nicht gefunden werden..

2 Lead the capillary into the connection

• Push the capillary end into the corresponding connection

until it reaches the stop (in order to avoid dead volume).

3 Tighten up compression fitting

• Tighten up compression fitting Fehler! Verweisquelle konnte

nicht gefunden werden. or Fehler! Verweisquelle konnte nicht

gefunden werden. by hand (do not use any tools).

With the versions 2.844.0030 and 2.844.0130, the connections from

the high-pressure pump to the detector consist of 6.2620.020 Steel

pieces are mounted on the capillaries as follows:

Steel capillaries fitted with new connectors must have a perfectly flat
