DETERMINATION OF ORGANIC ALKYL-HYDROPEROXIDE AND 1-HYDROXY HYDROPEROXIDE WITH CHEMILUMINESCENCE, FLUORESCENCE AND GC/MS

In this study three methods for the determination of peroxy compounds with HPLC are presented. The applicability of these methods with respect to atmospheric chemistry is discussed. In rain samples 1-hydroxy hydroperoxides are determined with a detection limit of 0.058-mu-mol/l. Alkyl hydroperoxides are determined in a mixture of hydrocarbon, hydrogen peroxide and air which has been irradiated with light before analysis. A new method for the detection of peroxides in such photolysis mixtures by GC/MS is presented.
