Design of experiments in liquid chromatography (HPLC) analysis of pharmaceuticals: analytics, applications, implications and future prospects

Abstract

AbstractThis review presents the essential brief annals, crucial analytics, precise applications and noteworthy implications of design of experiments which enrouted to liquid chromatography (LC) in the midst of utmost focus on high-performance liquid-chromatography (HPLC) and broadened its impressions on allied techniques in pharmaceutical analysis. Being most widely applied statistical methodologies for such purpose, its use was started in 1970 and heightened after Fischer’s precious input in 1981. The persistent use of statistical approaches one after another led to the efficient attention of pharmaceutical analysts. Hence, in order to fine-tune the trail impressed by the cumulative trends, the use of statistical designs in HPLC analysis has been reviewed and efforts were made to recognize its relative impact and corresponding future prospects. Applications of precise methodologies have been reassessed with respect to the need established by recent regulatory perspectives with a fanatical and the consequent stance on prominent historical advancements and concrete purposes. An effort was also made to state an arbitrary classification of diverse design types and succinct line of application in LC and associated analyses.
