what is the peak purity concept?
Answer Posted / raghavaiah mandalapu
Peak purity analysis is an evaluation technique for
detecting the presence of coeluting impurities in HPLC
data. Running a peak purity check prior to analytical
quantitation helps to ensure accuracy. In the development
of analytical methods, peak purity analysis can reveal the
presence of contamination during standardization and, by
doing so, can prevent the subsequent generation of false
analytical data.
Peak purity analysis is also a useful addition to routine
quality control procedures, especially in the analysis of
pharmaceuticals and food products, for which contamination
and quality of results are critical.
