How to Calibrate the Agilent 7693A Sample Tray

Answer

This Information Applies To: Agilent 7693A Automatic Liquid Sampler

Issue:

The Automatic Liquid Sampler (ALS) system calibration process aligns the sample tray with the injector turret position to enable vial transfers without incident.

Calibration should be performed if a calibration does not exist, as a routine maintenance procedure and is recommended if any ALS components are moved.

Do not confuse ALS alignment, with ALS calibration. During alignment, the ALS tray gantry will basically calibrate the X, Y, and Z axes. Calibration aligns the sample tray with the injector turret position.

Steps to follow

1.  Place the calibration vial part number G4514-40588 (Figure 1) in the tray position 1 (Figure 2).

2. Remove any vials from transfer turret positions L1, L2, and L3 for all installed injectors.

3. Start the ALS system calibration:

   • Intuvo 9000 GC: In the browser interface, or touch screen, select Settings > Calibration > ALS/Tray > Start Calibration.

   • 8890 GC: In the browser interface, or touch screen, select Settings > Calibration > ALS/Tray > Start Calibration.

   • 8860 GC: In the browser interface, select Settings > Calibration > ALS/Tray > Start Calibration.

   • 7890 Series GC: Use the GC front keypad and select [Options] Calibration > ALS > Start Calibration.

   • 6890N Series GC: Use the GC front keypad and select [Options] Calibration > Sample tray > Start Calibration.

   • 6890A/Plus Series GC: Use the GC front keypad and select [CONFIG] > Sample tray > Calibration > [START]

4. The following calibration process will occur for all installed injectors:

   1. The tray assesses the turret alignment by placing the calibration vial into turret position L1 and returning to sample tray position 1.

   2. The tray tests the vial height and turret position using the alignment tab between positions L1 and L2 on the transfer turret.

   3. The tray verifies the turret alignment by placing the calibration vial into turret position L1 and returning it to sample tray position 1.

5. When the calibration process is complete, the green Ready status light will come on and the gantry will stop in the Home position. Remember to replace any vials that were moved for the calibration process.
