Analytes - o-xylene

o-xylene: CAS No. 95-47-6, C8H10, molecular weight 106.16, boiling point 144.4°C, density 0.88gm/mL, vapor pressure 6.6mm Hg at 25°C, flash point 16°C, autoignition temperature 463°C, slightly water soluble is a colorless liquid used almost entirely in the manufacture of phthalic anhydride. A small amount is used in solvent applications and to make bactericides, soybean herbicides, and lube oil additives. 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.
