The automatic liquid sampler allows injection onto 250-µm and 320-µm
columns in addition to 530-µm columns.
This section explains how to adapt the GC and the automatic liquid sampler to
use the smaller columns. Specifically, it outlines the following:
• How to install the needle into the syringe barrel
• How to check the needle-to-column size
• How to prepare the inlet
• How to use retention gaps
• How to prepare the injector
• How to replace the needle guide in the needle support foot
• How to troubleshoot 250-µm and 320-µm injections
• How to control sample vial temperatures
• How to use tray control commands
For a list of the consumables needed to perform 250 µm and 320 µm injections,
see the Agilent analytical consumables and supplies catalog.
