Testing the Limits of Ion Mobility Mass Spectrometry to Compare a Nonbiological Complex Drug Product and Purported Generics—A Case Study with Copaxone

The analysis of oil samples containing many thousands of constituents best illustrates the benefits of ion mobility MS for complex samples. Here, we test the limits of ion mobility MS to discern differences between batches of Copaxone, a highly complex drug containing billions of peptides, and various purported generic versions of the drug.
