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!
Hi howard_sanford,
Problem solved!!!
My colleague changed the “Decimal symbol” and “Digit grouping symbol” in my computer, and my problem was solved. I am in Denmark, so the default “Decimal symbol” is a comma “,”. Now it has been changed to a period “.”. And the default “Digit grouping symbol” was changed from a period “.” to a comma “,”.
Maybe other European users should be aware of this potential problem.
Best,
Tny
