University of Babylon / College of Pharmacy Department of Pharmaceutical Chemistry/Analytical Chemistry Lecture number - 11 28/12/2018 STRUMENTAL METHOD: HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY OR HIGH-PRESSURE LIQUID CHROMATOGRAPHY • Is a chromatogrphic technique that can separate a mixture of compounds, and is used in biochemistry and analytical chemistry to identify , quantify and purify the individual components of the mixture. • HPLC utilizes different types of stationary phase [ typically , hydrophobic saturated carbon chains ] . • A pump that movse the mobile phase(s) and analyte through the column. • A detector that provides a characteristic retention time for the analyte , the detector may also provide other characteristic information ( i.e. UV / VIS spectroscopic data for analyte if so equipped). • Analyte retention time varies depending on the strength of its interactions with the stationary phase the ratio /composition of solvent (s) used and the flow rate of the mobile phase. • With HPLC , a pump (rather than gravity). • Provides the higher pressure required to propel the mobile phase and analyte through the densely packed column . the increased density arises from smaller particle sizes. This allows for a better separation on columns of shorter length when compared to ordinary column chromatography.
