Real-time volatiles analysis supports air quality modeling
SIFT-MS is supporting scientists committed to improving urban air quality, by providing the real-time VOC data necessary for building effective models. In addition to the high sensitivity of modern SIFT-MS instruments, the unique rapidly switchable reagent ion system enables a very wide range of VOCs and inorganic gases to be quantified in a single analysis.
Examples of compounds detectable using SIFT-MS are:
- Oxygenates, such as alcohols, aldehydes (including formaldehyde), and ketones (with real-time resolution of isomeric aldehydes and ketones)
- Nitrogen compounds, such as nitrous acid (HONO), peroxyacetyl nitrate (PAN), ammonia, amines and nitrosamines
- Halogenated compounds, such as hydrogen chloride, methyl bromide, and perchloroethylene
- Sulfur compounds, such as hydrogen sulfide, sulfur dioxide and carbonyl sulfide
