Applications for LCMS Methanol
LCMS Methanol is an ideal mobile phase solvent for both reversed phase and normal phase HPLC-MS. ProteoChem's highly refined LCMS grade Methanol is ideally suited for even the most critical LCMS applications.
ProteoChem's LCMS Methanol purity is ≥ 99.9% pure, contains very low levels of evaporative residue, and other ion suppressing materials, which is critical to achieving maximum sensitivity with LC-Mass Spectrometry. LCMS Methanol is purified to minimize any UV impurities, which ensures high sensitivity and minimal interference in HPLC applications with UV detection.
ProteoChem also offers an exceptionally high purity HPLC grade Methanol.
