Opis: This range of plates uses an optimised Merck silica gel 60 with a particle size of only 5 to 6 µm, which results in higher packing density and a smoother surface, therefore reducing band diffusion. Less sample is required, 0,1 to 0,5 µl than classic TLC.

Opis: 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.

Opis: Merck Multiformat plates are pre-scored glass plates for easy breaking into various sizes. The plates use the same silica coating as the corresponding TLC or HPTLC plate delivering chromatograms that are identical to those of the non scored plates.

Opis: TLC plates and sheets are used for the separations of alkaloids, steroids, aliphatic and aromatic compounds.

Dodávateľ: MACHEREY-NAGEL

Opis: Octadecyl-modified HPTLC silica glass plates are recommended for alkaloids, amino acids, preservatives, optical brighteners, barbiturates, polycyclic aromatic hydrocarbons (PAH), drugs, peptides, flavonoids, phenols, indole derivatives and steroids.

Opis: TLC plates, unmodified silica gel 60
This range of plates uses Merck silica gel 60 with a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. The smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 200 μm and, particle size of 10 to 12 µm. Flexible aluminium plates that can easily be cut to match individual separation requirements. Two inorganic fluorescent indicators for UV detection of colourless substances. Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching.

Opis: 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.

Dodávateľ: MACHEREY-NAGEL

Opis: Diol-modified HPTLC silica layers available as glass plate with fluorescent indicator. Recommended for steroids, pesticides and plant constituents;
for critical separations an alternative to silica, since it is less sensitive to the water content of the environment; leads to more reproducible results compared to silica.

Opis: Dimethyl-modified standard silica layers available as glass plates or ALUGRAM® aluminium sheets. Recommended for active plant constituents and steroids.

Dodávateľ: Merck

Opis: 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.
