When is HPLC Analysis Used in the Laboratory

HPLC analysis (high performance liquid chromatography) is a variety of chromatography which is often used in biochemistry and analytical chemistry laboratories whose purpose is to identify, separate and quantify compounds in a sample. The method is a type of column chromatography using a column which contains a chromatographic packing known as the stationary phase, a pump whose purpose is to move the mobile phase or phases through the column and a detector which is used to determine and display the retention time of the compounds in the column. The retention time (which is the time elapsed from introduction to elution) will vary based on the interactions of the analyte, the solvents used and the stationary phase in the column. In an HPLC, GC, GCMS analysis labs in Chennai procedure, a small volume of the sample is introduced to the mobile phase stream; the pace of progress of the analyte through the column will be quicker or slower depending on the physical and/or chemical interaction...
