HPTLC plates with spherical particles, LiChrospher®
Supplier: Merck
HPTLC LiChrospher® plates are based on spherical-shaped silica 60 with a particle size of 7 µm, and narrow particle size distribution similar to the phases used in HPLC. LiChrospher® HPTLC plates possess a selectivity that is comparable to respective HPTLC plates, however, plate height and separation numbers are further improved resulting in shorter analysis times.

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.

Dichloromethane stabilised, LiChrosolv® for HPLC, Supelco®
Supplier: Merck
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in 'gradient grade' as well as 'isocratic grade'. This minimises the gradient effect of the solvent involved.

TLC and GLP plates, silica gel 60, unmodified layers, glass backed
Supplier: Merck
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.

VWR® PESTINORM®, Gas Chromatography (GC) Certified Reference Material
Supplier: VWR Chemicals
Due to its excellent separation capacity and its high sensitivity gas chromatography is a widely used technique for analytical purposes. In order to get proper identification and quantification results of the analysed compounds, reference standards are needed. These PESTINORM® reference substances can be used for the characterisation of GC column properties. In addition they may also be used for the identification of unknown compounds in a gas chromatogram or as standards in quantitative GC analysis.
