9 Results for: "EUPROMOCHEM00001"

Supplier: Merck

LiChrosolv® hypergrade is accurately tested for LC-MS suitability, and meet all the requirements of modern LC-MS ionisation methods (ESI / APCI - positive and negative mode).

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.

Supplier: VWR Chemicals

VWR® PFAS grade LC-MS solvents undergo a rigorous use test to ensure suitability for analysis of poly- and perfluoroalkyl substances resulting in an ultra low background of PFAS analytes. Using complementary methods a broad range of PFAS analytes are quantified to their detection limits by LC-MS.

TLC plates, unmodified silica gel 60
This range of plates uses Merck silica gel 60 with a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. The smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 200 μm and, particle size of 10 to 12 µm. Flexible aluminium plates that can easily be cut to match individual separation requirements. Two inorganic fluorescent indicators for UV detection of colourless substances. Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching.
