Abstract
The development of an automated method for the simultaneous determinat ion of nitrogen oxides, aldehydes and ketones is described. All compon ents are sampled together by means of impingers, which are filled with an acidified solution of DNPH in acetonitrile. The corresponding deri vatives are separated and quantified by reversed-phase HPLC with UV de tection at 300 nm or at 345 nm. Using this reproducible method calibra tion curves with a correlation coefficient of 0.999 could be obtained. The method was validated by means of several field tests, measuring c andle smoke and cigarette smoke.
