Synthesis and Analysis of Organic Hydroperoxide by PTR-MS
EMSL Project ID
3364
Abstract
The aim of this proposal is to synthesize a few select organic hydroperoxides relevant to atmospheric chemistry and to measure them in the
gas phase by Proton Transfer Reaction Mass Spectrometry. The PTR-MS
measurements will evaluate the mass fragmentation pattern under different
collisional energies and establish the technique's sensitivity using a
Henry's Law calibration device. The goal is to evaluate PTR-MS suitability
for atmospheric measurements of hydroperoxides. What is required is the
synthesis of an aqueous methyl hydroperoxide (CH3OOH) solution at a
concentration of about 0.2-0.5 molar (determined by volumetric titration)
and measurement of the solution vapor by PTR-MS. The methylhydroperoxide
solution purity needs to be known prior to measurement by PTR-MS.
