Description: Unmodified HPTLC silica layers available as glass plates with or without fluorescent indicator. The narrow fractionation of the silica particles features theoretical plate heights, which are one order of magnitude smaller than on standard silica layers. Thus, Nano-ADAMANT has the advantage of sharper separations, shorter developing times, and increased detection sensitivity with equal selectivity.

Catalog Number: (MANA530018)
Supplier: MACHEREY-NAGEL
Description: These papers are made hydrophobic (impermeable to water) by impregnation with a silicone. With the aid of these filters, water can be separated from water-immiscible organic solvents in an elegant manner, by means of a simple filtration.
