Special considerations when using an integrator with a
6890 Series GC
The definitions of sequence are not the same in the 6890 Series GC and in the
3396 integrator. The following points must be considered when sequences are
used with this GC/integrator combination:
• The integrator has only one subsequence plus the priority sequence. Only
one GC method can be used within an integrator sequence.
• The automatic liquid sampler method parameters are prepared using the
[Front Injector] and [Back Injector] keys on the 6890 keyboard.
• The sample information table is prepared on the integrator.
• The injection sequence parameters can be prepared either with the [Seq]
key on the 6890 GC keyboard or in the [PREP][SEQ] dialog of the 3396.
Setting sequence parameters on either instrument changes the sequence in
both places.
• The Start sequence function on the GC is inactive.
• A sequence must be started from the integrator using [SEQ][START].
• If you use INET, pressing the stop key on either instrument stops the run
and aborts the sequence.
• If you use the part no. 03396-61010 cable instead of INET, the two stop
keys have different effects. The [STOP] key on the integrator stops the
current run and aborts the sequence. Stop on the GC stops the current run,
but the sequence continues as soon as the GC becomes ready.
For more information on the 6890 Series GC, see “Using Sequences” in the
Agilent 6890 Series Gas Chromatograph Operating Manual.
