Methyl blue microbiology stain (C.I. 42780)

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.

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.

Supplier: Merck

TLC plates, that feature a smooth and extremely dense plate coating, ensuring narrow bands and maximum separation efficiency with the lowest background noise. Flexible plastic sheets can easily be cut to match individual separation requirements.

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.
