3. Cap has a flat septum centered over the top of the vial.
• If the septum is not flat, remove the cap, turn the adjusting screw
clockwise, and try again.
• If the cap is not centered, remove the cap, and make sure the new cap
is flat on the top of the vial before you squeeze the crimper.
Figure 23. Acceptable and unacceptable caps
There are three reasons for crimping the cap properly:
• The syringe tends to core a curved vial septum and drop small pieces of
the material into the sample.
• The syringe needle could hit the metal part of the uncentered cap.
• The tray gripper may drop a vial if the cap has folds or wrinkles in it.
Placing sample vials in the standard injector turret
If you do not use the tray, you can place one, two, or three vials in the injector
turret. For two or three sample vials, you must convert some of the bottle
positions to sample vial positions with sample inserts.
1. Place the appropriate sample inserts in bottle positions 2 and 3 on the
turret.
• For one sample, no inserts are needed. Position one is molded into the
turret.
