Agilent 7673, 7683 and 7693 Autosampler on the 6890 GC
With the Agilent 6890 GC, the autosampler is controlled via the gas chromatograph.
7673 and 7683 ALS Autosamplers only
Note:
The necessary functionality is either already included (if the sticker ALS Ready is on the GC) or added with an external G1512A Controller Box, which is connected to the GC.

Injection range
Ensure the injection range is set correctly, depending on the GC and autosampler in use. Note that not all of the possible GC-autosampler combinations are mentioned below. If in doubt, please contact your Agilent or Thermo Fisher Scientific Service Representative for more information.
Tips:
7673 on the 6890 GC (The following applies to the 6890 GC, but not to the 6890N GC.): On the 6890 GC, check whether an injection range is set (Nanoliter adapt: On/Off under [Config] / [Front Injector]). If it is, verify that the same injection range is set both on the device and in Chromeleon. If the injection ranges are different, the actual injection volume will be different from the set volume. Set the injection volume in Chromeleon via the following sampler command:
Nanoliter = On / Off.
7683 on the 6890 GC
7683 on the 6890 GC: On the 6890 GC, set the injection range to Nanoliter adapt: On under [Config] / [Front Injector]. On the Sampler page in the Chromeleon Server Configuration, select 7673 ALS from the drop-down list.
7683 on the 6890N GC: On the 6890N GC, set the injection range to Nanoliter adapt: On under [Config] / [Front Injector]. On the Sampler page in the Chromeleon Server Configuration, select 7683 ALS from the list.
7693 on the 6890 GC and 6890N GC: The injection volume can be set in the range from 1%–50% of the syringe volume (in increments of 1%).
