Ready-to-use layers for TLC glass plates Thin layer chromatography is used for a wide range of analyses, and over the years it has become apparent, that there is no universal plate which meets all possible demands. For this reason our range of TLC ready-to-use layers is very versatile to cover many different types of applications. They have homogeneous, smooth, well adhering layers, an important criterion especially for reproducible quantitative evaluation.
Key features of TLC glass plates: - excellent separation efficiency - high Lot to Lot reproducibility - chemical resistance of glass support - ability to scan (absolute planarity, transparent support) - preparative TLC possible
TLC glass plates: Silica 60, specific surface (BET) ~ 500 m2/g, mean pore size 60 Å, specific pore volume 0.75 ml/g, particle size 5 – 17 μm, thickness of layer 0.25 - 2.00 mm
As fluorescent indicators we use manganese activated zinc silicate for short-wave UV light (254 nm) and a special inorganic fluorescent pigment for long wave UV light (366 nm). As binder highly polymeric products are used, which are stable in almost all organic solvents and resistant towards aggressive visualisation reagents.
Further TLC-products from MACHEREY-NAGEL: - plates with concentrating zone - plates and sheets with aluminium oxide or polyamide - plates and sheets with cellulose, MN 300 (native fibrous) MN 400 (microcrystalline cellulose plates), modified cellulose with ion exchanger - modified layers (CN, NH2, Diol) - further RP layers (Nano-SIL C18-50, Nano-SIL C18-100, RP-2) - CHIRALPLATE for enantiomeric separations - layers for special applications (PAH, tensides) - ion exchangers - mixed layers (aluminium oxide/cellulose, cellulose/silica, kieselguhr/silica) - visualisation reagents and accessories
