Introduction to Modern Liquid Chromatography, Third Edition part 83. High-performance liquid chromatography (HPLC) is today the leading technique for chemical analysis and related applications, with an ability to separate, analyze, and/or purify virtually any sample. Snyder and Kirkland's Introduction to Modern Liquid Chromatography has long represented the premier reference to HPLC. This Third Edition, with John Dolan as added coauthor, addresses important improvements in columns and equipment, as well as major advances in our understanding of HPLC separation, our ability to solve problems that were troublesome in the past, and the application of HPLC for new kinds of samples. . | 776 SAMPLE PREPARATION micropipette tip 96-well SPE plate coated fibers a stir-bar sorbent extraction The micropm Cto tpp MPT format Fig. permits the handling of submicroliter amounts of sample such as biological fluids.
