Iam using Agilent 5975 ms, coupled with Headspace while doing identification of Unknown in a sample the system -peak(o2) arising when crimping the vial, merges with the analyte.

Kindly share the ideas how we can avoid the same.

Can you retain your analyte? It can be done by programming or dif. column.
Can you get rid of o2 by purging vial with He? Traces can be eliminated by o2 absorbing chemistry if applicable.
Can you do scanning above m/z of o2?
