The following document outlines how to utilize ACD/Spectrus Processor for Potency in NMR. ACD/Labs provides a scripted solution for the problem of determining weight percent purity (WPP) by NMR. The result of this kind of measurement is widely used in the pharmaceutical industry to determine very exact concentrations of materials for use as standards or in delicate, accurate analyses. It is also sometimes known as “Potency” or “Strength”. The accompanying script for this guide can be found in the Training Resources section of the portal.
