Methanol ≥99,9%, HiPerSolv CHROMANORM®, PFAS-Qualität für die LC-MS
Methanol
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.
- Specifically tested for PFAS analysis
- Ultra low background solvent for LC-MS analysis of PFAS (poly- and perfluoroalkyl substances)
