TLC and GLP plates, silica gel 60, unmodified layers, glass backed

Supplier: Merck
Description: TLC plates, unmodified silica gel 60
Merck silica gel 60 has a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. This smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 250 μm and particle size of 10 to 12 µm. Two inorganic fluorescent indicators for UV detection of colourless substances.

TLC plates, silica gel 60, unmodified and chemically modified layers, aluminium backed

Supplier: Merck
Description: 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.

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

Supplier: Merck
Description: 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.
