Replace the chromatograph columns
The chromatograph columns should be replaced as a set. The tubing
connectors use a unique double o-ring sealing arrangement. The bolt
on the tubing connectors should only need to be loosened to facilitate
removing the columns, and should not be removed unless the o-rings
are to be replaced.
6.8.1
Installation
1.
Use the 4 millimeter hex or allen wrench to loosen each of the
tubing connector bolts by a ½ turn only.
NOTICE
Do not remove the bolt from the tube connector fitting, because the o-rings and
spacers will come out of the fitting.
2.
Carefully pull each column end from the tubing connectors.
3.
Discard the old columns.
4.
Install the new columns:
(a.)
Insert each column into the appropriate connectors
according to the markings on the manifold plate and the
tag on the column. See
“Column assignments” on
page 6-39
and
“Column drawings” on page 6-39
for help
matching the column with the column connectors.
Parts required
A 370XA C6+ 4-minute column set (# 7A00101G01).
Tools required
A 4 mm hex or allen wrench
