TOGA-TOF

High Resolution Time-of-Flight TOGA System

The TOGA-TOF system paired our TOGA instrumentation with a high resolution electron impact time-of-flight (HR-EI-TOF) mass spectrometer (Tofwerk). The TOGA-TOF allows for greater selectivity, increased VOC separation in polluted and complex atmospheric mixtures resulting in more accurate measurements of a wider range of hard-to-measure gases including oxygenated VOCs, biogenic VOCs, organic nitrates, nitriles, and halogen-containing VOCs. It has allowed us to identify and quantify new species not previously targeted for analysis.
