HPTLC plates with spherical particles, LiChrospher®

HPTLC plates with spherical particles, LiChrospher®

Supplier: Merck

HPTLC LiChrospher® plates are based on spherical-shaped silica 60 with a particle size of 7 µm, and narrow particle size distribution similar to the phases used in HPLC. LiChrospher® HPTLC plates possess a selectivity that is comparable to respective HPTLC plates, however, plate height and separation numbers are further improved resulting in shorter analysis times.

HPTLC plates silica gel 60, RP-modified layers, glass backed

HPTLC plates silica gel 60, RP-modified layers, glass backed

Supplier: Merck

Our NH₂, CN- and DIOL-modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An alternative to PEI cellulose, amino-modified NH₂ plates provide weak basic ion exchange characteristics with special selectivity for charged compounds.

TLC plates, silica gel 60, modified layers, glass backed

TLC plates, silica gel 60, modified layers, glass backed

Supplier: Merck

RP-2, RP-8 and RP-18 are based on silica gel 60 modified with aliphatic hydrocarbons. The chain length, in combination with the degree of modification, defines the ability to tolerate water in the solvent system and strongly affects retention. Migration time increases in the order RP-2, RP-8 and RP-18 using the same solvent composition. RP-8 and RP-18 can be run with up to 60% water in the solvent system.
