摘要：

The collection of low-boiling olefinic aldehydes on 2,4-dinitrophenylhydrazine (DNPH)-coated adsorbents (silica cartridges and glass denuders) is examined. Concurrent formation of two different hydrazones by both acrolein and crotonaldehyde is reported and discussed. Identification and quantitation of these compounds do not represent a problem in HPLC analysis, because of their separation from other C-3 and C-4 carbonyl derivatives present in airborne sample extracts.
