Aligning the Sampling Needle in the Inject Port

Align the sampling needle in the inject port at the following times:

•

After replacing the sampling needle assembly (see

Section 5.4

) and/or the

needle seal assembly (see

Section 5.7

)

•

If the needle becomes misaligned

NOTE Before aligning the sampling needle, always inspect the

needle to make sure it is not bent. If the needle is bent,
replace the sampling needle assembly (see

Section 5.4

Two methods are available for aligning the sampling needle:

•

Automatic alignment, using Chromeleon or Chromeleon Xpress (Release 6.8
SP2 or later)

•

Manual alignment, using the AS front panel screens

This section describes the alignment procedure in Chromeleon or Chromeleon
Xpress.

If Chromeleon or Chromeleon Xpress (Release 6.8 SP2 or later) is unavailable,
refer to

Section D.8

for instructions on how to use the front panel screens to align

the needle.
