TOGA is a fast gas chromatograph combined with a mass spectrometer (MS). TOGA provides atmospheric mixing ratios of an extensive and growing list of compounds, nearly any organic species in the C2-C10 molecular structure range. The list includes alkanes, alkenes, alkynes, chlorofluorocarbons, halons, plus reactive oxygenated species such as alcohols, ketones, esters, and acids. Typically, a subset of some 40 different trace gases are measured, all at sensitivity to levels that occur in the atmosphere.
