Instrument

TOGA
Trace Organic Gas Analyzer

The Trace Organic Gas Analyzer (TOGA) is an in situ airborne analyzer that measures volatile organic compounds (VOCs) in the atmosphere. It uses a combination of fast gas chromatography and mass spectroscopy to provide atmospheric mixing ratios of VOCs. It can detect a wide range of VOCs with high precision (<3%) and accuracy (20% or better) at a time resolution of 40 seconds for a 2-minute cycle.
