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.

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).

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.
Click the sample loop cartridge in the designated location and keep the right orientation.
Install the shorter capillary of the sample loop cartridge to the analytical head.
Pinch and reinsert the needle assembly and the connected sample loop capillary into the z- arm coupler.

NOTE
Check the tension of the loop capillary. This must be forced and guided to the hydraulic box to prevent it from being caught by the Z-drive.
In the Local Controller close Change needle /seat.

OR

In Agilent Lab Advisor software Change needle/loop. Click NEXT and wait until the needle is in the needle park station.

Click Back to leave the Maintenance window.

NOTE
If you need an autoreferencing step included, you must choose the change needle procedure.

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).
