  • Instrument and process for testing landfill gas for chlorinated hydrocarbons
    Patent number: 4521225
    Abstract: A method for determining the concentration of chlorinated hydrocarbons in landfill gas by injecting a carrier gas and landfill gas containing chlorinated hydrocarbons through a valve and into a gas chromatographic column containing a column packing capable of separating the chlorinated hydrocarbons. The temperature of the column is appropriately controlled to bring about the elution of the chlorinated hydrocarbons so that the concentration of the chlorinated hydrocarbons can be determined. The valve is a multiple port valve which permits loading of the landfill gas into the valve and subsequent injection of the landfill gas and the carrier gas into the column.
