Prerequisites

WARNING

Risk of injury by uncovered needle

An uncovered needle is a risk of harm to the operator.

CAUTION

Mismatching sample loop configuration

Damage to the system

Make sure, that the sample loop configuration matches to the hardware installed.

CAUTION
Blockages inside of the needle assembly union
- Do not overtighten the fitting. A quarter turn should be sufficient.
Use a 1/4-inch wrench to tighten the fitting of the loop capillary.
Close the front door.
In the Local Controller close Change loop.

OR

In the Agilent Lab Advisor software Change Loop, click Back and wait until the needle is in the needle park station.

NOTE
Choose the Change Needle procedure, if you need an auto referencing step included.

NOTE
If you have changed the sample loop, verify that the correct sample loop is configured in the CDS, see Setting Up the Autosampler With OpenLab ChemStation.
For G7167C and G7137B, proceed with the subsequent steps.
Perform Hydraulic Path Leak Test.
Perform Sampler Leak Test if needed for troubleshooting in case of Hydraulic Path Leak failure.
