Correcting sample vial delivery problems

When you find a mishandled sample vial, check:

❒

Are there folds or wrinkles in the crimp cap, especially near the neck of the

sample vial? For more information, see your

Operation Guide

and your

Sampling Techniques

Handbook

.

❒

Are you using the correct sample vials? Is the distance from the vial bottom

to the top of the neck about 28.4 mm? Is the bottle neck diameter

8.2 ± 0.3 mm? For more information, see your

Operation Guide

.

❒

If you use labels on the sample vials, are they the correct size? For more

information, see your

Operation Guide

.

❒

If you use labels on the sample vials, are they interfering with the gripper?

For more information, see your

Operation Guide

.

❒

Are there any obstacles to the tray arm or injector turret motions? Remove

any obstacles.

❒

Are the tray quadrants and turret in good condition? Clean any residue from

the sample positions. Temperature-controlled liquid pumped through the

quadrants, may cause quadrant distortion over time. See your

Operation

Guide

.
