A properly capped and sealed vial is critical in maintaining sample integrity during headspace autosampling. The
following are guidelines for proper vial preparation.
Figure 3-1: Properly Sealed Vial
When a vial is undercrimped, the cap shape will be concave and the cap can be easily rotated. The "tuck-under" on the
vial will be at an angle, not in contact with the underside of the collar. If you feel some resistance when trying to rotate
the cap, it is probably sufficiently crimped.
