Determination of organic alkyl- and 1-hydroxy hydroperoxides with chemiluminescence, fluorescence and GC/MS

Summary 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 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.
