TLC Plates

TLC plates are crucial in analyzing mixtures through compound separation to identify the quantity and purity. Product appearances or reactant disappearances are easily observed to show reaction progress. Pre-coated with a thin, uniform layer of solid absorbent, the TLC plates support accurate and reproducible conclusions. Choose from standard sized glass, metal, or plastic constructions compatible with manual or automated testing. Pore sizes may vary among models. Select styles may feature fluorescent indicator for colorless compounds.

HPTLC plates silica gel 60, modified CN, DIOL, NH₂, glass backed

Supplier: Merck

CN- and DIOL-modified silica plates are moderately polar that are suitable for both normal and reversed phase systems. The amino modified NH₂ plate provides weak basic ion exchange characteristics with special selectivity for charged compounds offering an alternative to PEI cellulose.

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 silica gel 60, unmodified layers, glass backed, LuxPlate®

Supplier: Merck

The LuxPlate® range of high fluorescence TLC plates contains an increased amount of fluorescent dye making it easier to identify small amounts of isolated material. Furthermore, the amount of binder added is elevated, resulting in a significantly brighter TLC plate with an even more stable and robust surface.

HPTLC and TLC plates, silica gel 60, MS-grade

Supplier: Merck

Coupling TLC plates to mass spectrometry is a new field of high interest, which will contribute strongly to the progress of planar chromatography. The MS-grade plates are much cleaner than standard TLC/HPTLC plates providing higher sensitivity and reduced background signals. This allows trace analysis with mass spectrometry detection in lower nanogram range.

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

Supplier: Merck

HPTLC plates, unmodified silica gel 60
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 for classic TLC.

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.

TLC plates, aluminium oxide 60

Supplier: Merck

Merck TLC aluminium oxide plates use neutral or basic aluminium oxide of 60 or 150 Å pore size with or without fluorescent indicator to suit different application needs. Under aqueous conditions, basic compounds can be best separated on basic aluminium oxide plates, while neutral compounds are best separated on neutral plates.

TLC plates, kieselguhr and mixed layers

Supplier: Merck

Kieselguhr is a natural diatomaceous earth that can be used for the separation of polar or moderately polar compounds. For the mixed layer plates a combination of classical silica gel 60 and kieselguhr is used, providing favorable properties for certain applications such as separations of inorganic ions, herbicides or steroids.

Multiformat plates, silica gel 60, unmodified layers, glass backed

Supplier: Merck

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.
