Notes:
A diverse mixture of volatile headspace analytes containing compounds with boiling points covering a range from -196°c to 145°c can be separated in approximately 40 minutes by multidimensional HRGC. The described provisional MD-HRGC Systems employ cryogenic sample collection, four 0.53 mm FSOT columns, and multi-ramp temperature programming of either one or two ovens. Enhanced sensitivity for organic species and minimal interference from water vapour in the samples can be obtained by a MD-HRGC configuration that uses separate ovens, appropriate column switching operations, and TCD + FID detection.
