Development of methods and procedures for monitoring ambient concentrations of oxygenated hydrocarbons. Final report
Technical Report
·
OSTI ID:128177
A method was developed and tested to measure ambient air concentrations of oxygenated hydrocarbons (carbonyls, alcohols and ethers) at parts per billion (ppb) levels. The method involves collecting a sample on a sorbent tube, extracting the sample with a solvent and analyzing the sample with two dimensional gas chromatography using intermediate cryogenic trapping and detection by an oxygen specific detector (O-FID). The method was developed using six compounds - acetaldehyde, methanol, acetone, MTBE, butanol, and methyl ethyl ketone. With the possible exception of methanol all of the species were accurately detected using the developed methodology.
