GCxGC/MS Facility for Multidisciplinary Applications

This lab has a Shimadzu GCxGC/MS system coupled to a Zoex modulator which is capable to measure a large suite of volatile organic compounds (VOCs). For offline sampling the lab has 75 1-L stainless steel canisters and a Perkin-Elmer adsorption tube sampler. The system is complemented by a PICARRO G2201-i CRDS (cavity-ring-down spectrometer) instrument to measure methane (CH4) and carbon dioxide (CO2) along with their 13C and 12C isotopes to distinguish among different carbon pools.

The lab is open to serve internal and external users in the field of atmospheric composition, emission sources, energy transformation, exposure studies and medical sciences.

Current work addresses unconventional sources for reactive organic carbon (ROC), per- and polyfluoroalkyl substances (PFAS) and phthalates.
