High Pressure Liquid Chromatography High pressure liquid chromatography can be used as a screening procedure instead of radioimmunoassay, although it is less sensitive. Extract 10 ml of urine with 25 ml of methylene chloride, separate the solvent layer, and dry it over anhydrous sodium sulphate. Examine 10 al of the extract using a silica column (Zorbax SIL, 5 am) (System HT, p. 219).

XAD resins have been used to collect and concentrate organic materials from seawater. They can also be used as packings for fractionation by column chromatography. While they have been used in simple gravity flow column chromatography, high pressure liquid chromatography has also been used [74-78].
