A high flow solid sorbent dynamic sampling method for ppb (v/v) airborne aldehydes and ketones was based on their chemisorption to 10% (w/w) O- (2.3,4,5.6-pentafluorobenzyl) hydroxylamine hydrochloride (PFBHA) on Tenax TA. The method is to be used for both ambient outdoor and indoor air. Fifteen carbonyl compounds were studied as target chemicals (acetaldehyde, acetophenone. acrolein, formaldehyde, isophorone, 2-butanone. hexone. propionaldehyde, benzaldehyde, butanal. 2-furaldehyde. isovaleraldehyde, n-valeraldehyde. acetone, and nhexaldehyde). Temperature and RH had no influence on the sampling efficiency. The PFBHA O-oximes of the target carbonyl compounds were synthesized. An optimal gas chromatography (GC) temperature program was developed to separate the PFBHA O- oximes mixture of all the target carbonyl compounds.
