Instrument Development


Oxygenated volatile organic compounds (or OVOCs) are important atmospheric species that can impact air quality and climate, yet they are notoriously difficult to measure. At Caltech, I helped developed novel instrumentation that allows us to observe real-time changes in the isomer distributions of a number of important OVOCs through a combination of low-pressure gas chromatography (GC) and fast response chemical ionization mass spectrometry (CIMS). Since its development in 2016, its participation in both laboratory and field studies has provided valuable data that can be used to elucidate the chemical mechanisms for a variety of important atmospheric species.
