Fibrous cellulose impregnated with polyethyleneimine available as POLYGRAM® polyester sheets with or without fluorescent indicator. They are used in analysis of nucleic acids and of mutagenic substances with the ³²P post labelling procedure.

Supplier: MACHEREY-NAGEL

Polyamide 6 layers are available as POLYGRAM® polyester sheets with or without fluorescent indicator. The separation mechanism based on hydrogen bonds to amide groups of the polymer matrix as well as on ionic, dipol and electron donor/acceptor interactions.

Supplier: MACHEREY-NAGEL

These native fibrous cellulose layers are available as glass plates, POLYGRAM® polyester sheets and ALUGRAM® aluminium sheets. They are used in partition chromatography of polar substances such as for the separations of amino acids, carboxylic acids or carbohydrates.

Supplier: MACHEREY-NAGEL

These are unmodified standard silica layers for TLC with a different binder system compared to SIL G. That results in a different separation characteristic.

Supplier: MACHEREY-NAGEL

These unmodified standard silica layers for TLC are available as glass plates with or without fluorescent indicator. High suitability for trace analyses resulting from a UV indicator with increased brilliance and a low-noise background of the layer.

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.

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.

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.

Supplier: Merck

Les plaques de silice modifiées CN et DIOL sont modérément polaires et adaptées aux systèmes en phase normale et en phase inversée. La plaque modifiée NH₂ offre des caractéristiques d'échanges d'ions faiblement basiques avec une sélectivité spéciale pour les composés chargés. Elle peut remplacer la cellulose PEI.

Supplier: VWR Collection

Ces plaques de verre HPTLC présentent une excellente efficacité de séparation grâce à une distribution optimisée de la taille des particules.

Supplier: Merck

Les plaques HPTLC LiChrospher® sont basées sur de la silice 60 de forme sphérique avec une taille de particule de 7 µm et une distribution granulométrique étroite similaire aux phases utilisées en HPLC. Les plaques HPTLC LiChrospher® possèdent une sélectivité comparable aux plaques HPTLC respectives, cependant, la hauteur de la plaque et les nombres de séparation sont encore améliorés, ce qui entraîne des temps d'analyse plus courts.

Supplier: VWR Collection

Ces plaques de verre HPTLC utilisent une taille de particules optimisée permettant une meilleure efficacité de séparation.

Supplier: VWR Collection

Les couches de silice modifiées sont, selon la modification, adaptées aux éluants polaires ou non polaires ou aux mélanges d’éluants.

Supplier: MACHEREY-NAGEL

Unmodified HPTLC silica layers with concentrating zone for HPTLC.

Supplier: MACHEREY-NAGEL

These unmodified HPTLC silica layers are available as glass plates with or without fluorescent indicator. The narrow fractionation of the silica particles features sharper separations, shorter developing times, and an increased detection sensitivity compared to DURASIL plates.

Supplier: MACHEREY-NAGEL

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.

Supplier: MACHEREY-NAGEL

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.

Supplier: MACHEREY-NAGEL

These are special TLC layers of silica mixed with ion exchange resins available as two different layers, both containing an inert organic binder.

Supplier: MACHEREY-NAGEL
