Chemical ionization tandem mass spectrometer for the in situ measurement of methyl hydrogen peroxide [PDF]

, 2010
A new approach for measuring gas-phase methyl hydrogen peroxide [(MHP) CH_3OOH] utilizing chemical ionization mass spectrometry is presented. Tandem mass spectrometry is used to avoid mass interferences that hindered previous attempts to measure ...
