Sigma Aldrich COA reports Area Percent by HPLC analysis. Knowing (or believing that I know) that the response factors for HPLC-UV can vary considerably... the fundamental question is: how much confidence to place in an analysis where I weigh out grams and make an assay correction on that gram weight for the assay based upon an HPLC certificate of analysis. Then proceed to run my analysis on a GC with FID detector.
