Analytes - tetrachloroethene
tetrachlorethene (perchloroethylene): CAS No. 127-18-4, C2Cl4, molecular weight 165.83, boiling point 121.3°C, density 1.62gm/mL, vapor pressure 18.5mm Hg at 25°C, non flammable, slightly water soluble is a colorless liquid used in insulating fluid and cooling gas in electric transformers, both cold cleaning and vapor degreasing of metals. It is most frequently measured in water, air, oil and soil to comply with environmental regulations. Due to its volatility, it is most often measured using GC/PID, FID, ELCD and GC/MS methods specified by regulatory agencies like the U.S. EPA.
