Analytes - methanol
methanol: CAS No. 67-56-1, CH4O, molecular weight 32.04, boiling point 64.7°C, density 0.81gm/mL, vapor pressure 127mm Hg at 25°C, flash point 12°C, autoignition temperature 464°C completely miscible with water is a colorless liquid with numerous and widespread uses including as an industrial solvent, a raw material for making formaldehyde and methyl esters of organic and inorganic acids, antifreeze for automotive radiators and brakes; ingredient of gasoline and diesel oil antifreezes, an octane booster in gasoline, as fuel for picnic stoves and soldering torches, an extractant for animal and vegetable oils, to denature ethanol and as a solvent in the manufacture of cholesterol, streptomycin, vitamins, hormones, and other pharmaceuticals. It is most frequently measured in water, air and soil to comply with environmental regulations. Due to its volatility, it is most often measured using GC/PID, FID and GC/MS methods specified by regulatory agencies like the U.S. EPA.
