A rapid, sensitive, and precise analytical method was developed for measuring the fractional amounts of the (−) and (+) forms of chiral enantiomeric forms of monoterpenes in air containing biogenic plant emissions. The method uses passive air sampling onto adsorption–thermal desorption (ATD) gas sampling cartridge tubes; this is followed by automatable thermal desorption onto a chiral gas chromatography (GC) column, followed by detection with mass spectrometry (MS).
