I have two unknown peaks on my GC (both with the same MW or rather highest M/Z ratio peak = 98) and I am trying to confirm their identity.
Based on the expected chemistry I have identified two potential candidate molecules from a library of GCMS spectra (see images below; just click on the images please if you cannot read the smaller font numbers).
Is it safe to think these are matches or not really? The MS was run in EI+ mode.
- Unknown-1 is Compund-B?
- Unknown-2 is Compound-A?
Both likely? Neither likely? Any one likely?
Is having the same set of M/z fragments good enough (e.g. 98-83-55 similar between Unknown-1 & Compound-B) or ought the abundance ratios also match mostly?
