Now, for the first time, a series of organosilane derivatized sorbents with varying hydrocarbon lengths, RP-2, RP-8 or RP-18. is available for reversed phase chromatography. They've just been introduced by the world's leader in chromatography—E. Merck, Darmstadt, Germany. • For the HPLC user, these new packings can mean optimized efficiency. Obtain "Chromatographic Flexibility in Reversed Phase Chromatography" by selecting the RP packing which best fits your sample/solvent parameters. • For the thin layer and column chromatographer, these sorbents are available on pre-coated TLC plates and for columns; they represent the introduction of reversed phase chromatography in
your disciplines. They are especially suitable when negligible polarity differences exist between components being separated, • Reversed Phase pre-coated TLC plates are also ideal tools for the chromatographer to evaluate sample/solvent combinations prior to High Speed Liquid Chromatography. No chromatographer is up to date unless he has information on these important new products. EM Laboratories' chromatography catalog has the facts you need. Send for your copy today by circling the reader service number indicated below. You'll see why RP-2, RP-8 and RP-18 deserve "Best of Show" honors in Reversed Phase Chromatography.
