The main aim of degradation study is to separate know
impurities in the case when we do not have know impurities
or to generate impurities from the sample by degradation.
Obviously one should know the process related impurities or
the degradation pathways. From peak purity by PDA or Mass
analysis one can conclude the purity of each peak eluting,
beyond that mass balance also account for peaks.If mass is
not balanced then one can conclude that some of the compound
are not eluted or may not have UV absorption.
