An inexpensive, rugged, and portable flame ionization detector has been designed for the continuous analysis of trace amounts of hydrocarbons. The detector is insensitive to inorganic gases but responds to hydrocarbons in proportion to the carbon atom content. A detectable limit of 1 p.p.b. of hexane is obtainable. As an automotive exhaust analyzer, the unit can first measure total unburned hydrocarbons, and then by introducing an 8-inch silica gel column, the unit can determine methane, ethane, ethylene, acetylene, and propylene. © 1960, American Chemical Society.
