Methanol ≥99.90%, CHROMASOLV™ for LC-MS, Riedel-de Haën™

Methanol (CH3OH) is also known as Methyl Alcohol or wood alcohol. It is a clear, colorless, volatile and flammable liquid. Methanol is a common laboratory solvent and is especially useful for HPLC, UV/VIS spectroscopy, due to its low UV cutoff. Methanol is toxic if ingested and can result in blindness, coma and death. Suitable for LC-MS applications and spectrophotometry.

  • For LC-MS and LC-UV trace metals analysis
  • HPLC / UV-VIS quality control
  • Low gradient baseline drift
  • Low levels of trace metals
