Purity estimation by ESI-Mass spec reflects the relative amount of the target molecule with respect to total amount of molecules in the sample that are all ionized in the positive ion mode (when protonated by formic acid), excluding negative molecules. High purity means less other molecules present in the sample, low purity may or may not related to the efficacy of the molecule if other molecules are having no antagonist activity. There should be a concern from low purity sample where degradation products, or derivatives from active component are abundant and whose biological activities are unknown, which also indicates the quality in the process chemistry in manufacturing the product. So high purity is desired, but low purity if other molecules contributed no biological activity, then is ok, There are other labs that can be done that will differentiate between "active" and "non active" antagonist elements. This lab costs more. I do not think your "talking shit" or anything like that I respect your asking these questions! I will try to do what I can within my power to answer your questions to the best of my ability. PM me and we can discuss further if you desire. I honestly look forward to these questions. The more we ALL understand the better the information and ultimately the better the decision on WHAT to get and from WHOM.

It has not landed yet. I was expecting some, but nothing yet.
