2 Connection needle – pump tubing 10
x Mount a PEEK compression fitting 6
666 on both ends of the
PTFE capillary 8
888.
x Screw the PTFE capillary 8
888 with the PEEK compression fitting
on to the PEEK compression fitting 5
555 already mounted on
needle holder 4
444 (see Fig. 6).
x Insert PTFE capillary into the guide chain 9
999 (see Fig. 1 and
section 2.3.10).
x Screw a coupling 19
