Title: GCMS predictions
Post by: nbhan on October 17, 2014, 01:41:35 PM
We are using an Agilent triple quad as a single quad to run central carbon metabolites, after derivatization. I was wondering if the predictions we obtain from XCMS online are correct as the molecular weights that are getting associated with the predictions are not of derivatized products. For example, the peak associated with glucose-6-phosphate has the molecular weight of glucose-6-phosphate and not the derivatized glucose-6-phosphate.

Thanks,
