Supplier: MACHEREY-NAGEL

Le liant hautement polymérique utilisé pour ces feuilles est stable dans la plupart des solvants organiques agressifs et résiste aux réactifs de visualisation agressifs. Il est également parfaitement stable dans les éluants purement aqueux.

Supplier: MACHEREY-NAGEL

Unmodified standard silica layers for TLC.

Supplier: MACHEREY-NAGEL

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

Supplier: MACHEREY-NAGEL

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

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.

Supplier: MACHEREY-NAGEL

These unmodified standard silica layers for TLC are available as glass plates with or without fluorescent indicator.

Supplier: MACHEREY-NAGEL

These glass plates with a special layer are used for TLC enantiomer separations (e.g. amino acids, thiazolidine derivatives, dipeptides, lactones, α-hydroxycarboxylic acids).

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 TLC plates and sheets are prepared by hydrolysis of high purity cellulose with HCl. They are used for carboxylic acids, lower alcohols, urea and purine derivatives.

Supplier: MACHEREY-NAGEL

Glass plates with mixed layers for TLC.

Supplier: CAMAG

TLC precoated sheets, silica gel 60.

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

Unmodified standard silica layers with concentrating zone for TLC.

Supplier: MACHEREY-NAGEL

Unmodified standard silica layers with "High Definition" properties for TLC.

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

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

Glass plates with a special special HPTLC silica layer for PAH analysis.

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

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.

Supplier: MACHEREY-NAGEL

Octadecyl-modified HPTLC silica layers available as glass plates or ALUGRAM® aluminium sheets. Recommended for aminophenol, barbiturates, preservatives, nucleobases, polycyclic aromatic, hydrocarbons, steroids, tetracyclines, and plasticisers (phthalates).
