Acetonitrile ≥99.9% (by GC), CHROMASOLV™ LC-MS Ultra tested for UHPLC-MS, tested for UHPLC-MS, Riedel-de Haën™

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 enables to minimize 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.

Supplier: Honeywell Chemicals

High purity solvents for speciation analysis by LC-ICP-MS. Rigorous purification procedures followed by UV spectroscopy, IC, and ICP-MS testing to assure high chemical purity and high UV transmittance. The blank values for metal traces in these solvents are in the ppb range or lower.

Supplier: MACHEREY-NAGEL

QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage color scale. The test strips are intended for single use, maintenance or calibration are not required.

Supplier: Merck
