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 combines fast gas chromatography and mass spectrometry to determine atmospheric mixing ratios of VOCs. It detects a wide range of VOCs with high precision (<3%) and accuracy (20% or better), with a time resolution of 40 seconds per 2-minute cycle.
