The Automatic Liquid Sampler
There are two Agilent automatic liquid sampler (ALS) systems available for the
6890 GC, the 7673 and the 7683. Refer to the ALS compatibility matrix below.
Table 23 ALS Compatibility Matrix
Note that once a G2612A ALS Interface board is installed, that GC can use only
the 7683 ALS.
Part 1. The 7673 ALS
This section contains information on how to configure and use your 7673 ALS.
The automatic liquid sampler system can include one or two injector towers, a
bar code reader, and a tray. You use the GC keyboard to enter injector and tray
setpoints and to control simple sequences. The system requires an G1512A
controller module. The parts of the sampler are:
• Injector tower—houses a 5-µl or 10-µl syringe for sample injection. Two
towers can be mounted for injection into both inlets. The tower can be lifted
off the inlet and parked on posts at the back of the GC.
• Sample tray—holds a maximum of 100 sample vials.
• Injector turret—holds sample, waste, and wash vials.
• Bar code reader—reads and decodes several different bar codes.
For more information on the 6890 automatic liquid sampler, refer to its
Operating Manual (Part no.07673-90187).
