I am using Agilent MassHunter Qualitative Analysis B.07.00 and NIST MS Search 2.2. I try to identify the peaks using NIST library. This is the mass spectrum of a peak of interest:
But when I tried to do NIST search, a completely different spectrum appeared in NIST, but with the right retention time showing as the title of the spectrum:
If I click the next scan of the same peak, I got the same mass spectrum as the previous scan:
But when I did NIST search, another completely different spectrum appeared:
Neither of the NIST search resutls gave me the right identification of that peak.
How can I solved the problem? How can I get the correct spectrum pass to NIST MS Search?
Thank you in advance!
