This column is a continuation of the set we have been working on to explain and derive the equations behind principal components (1–5). As we usually do, when we continue the discussion of a topic through more than one column, we continue the numbering of equations from where we left off.

Mass spectrometry (MS) is a broadly used analytical technique that is often combined with some form of chromatography to provide a second dimension of separation. However, vendors recently have begun incorporating ion mobility separation (IMS) into high-end LC–MS instruments, thus providing an additional level of ion separation.
