Our LC/MS (Liquid chromatography-mass spectrometry) Grade Methanol is ultra-purified and low UV-absorbent. This makes it suitable for chromatography and mass spectrometry applications. LC-MS grade solvents are chemically "cleaner" than HPLC grade solvents. Impurities in a solvent can be detrimental to the precision and reproducibility of analytical findings because of the high sensitivity of analytical techniques such as LC/MS. Our premium quality LS/MS grade Methanol is certified by the American Chemical Society (ACS) and highly recommended for obtaining consistent and repetitive results in research labs.
