Enhanced Tailpipe, Material Emission, and Leak Analysis with SIFT-MS
Regulators and consumers demand increasingly lower levels of gaseous emissions from diverse automotive and aerospace sources, such as combustion exhaust, component emissions, and leakage. Emission compositions vary widely between sources but frequently consist of both volatile organic compounds (VOCs) and inorganic gases.
Speciation and quantitation of these emissions at increasing lower levels are challenges for existing process monitoring instruments, while conventional laboratory analytical technologies are not configurable for such applications and are expensive, complex, and slow, since they are based on chromatographic methods.
This 60-minute Webinar introduces Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) – an innovative, industry-proven analytical technique that directly and instantly analyzes air down to part-per-trillion (ppt) concentrations. By applying eight rapidly switchable chemical ionization agents, one SIFT-MS instrument can selectively and quantitatively analyze a very diverse range of compounds in one analysis including:
- VOCs (e.g., acetic acid, benzene, formaldehyde, isooctane)
- Inorganic gases (e.g., ammonia, carbon dioxide, hydrogen sulfide)
- Acidic gases (e.g., hydrogen chloride, nitrogen dioxide, sulfur dioxide)
- Water vapor
Various applications of SIFT-MS are described in the Webinar, including enhanced tailpipe exhaust gas analysis, emission screening of synthetic and natural vehicle components, and leak detection. Implementations of SIFT-MS instrumentation range from R&D to the process line, enabling timely decisions to be made from new product development right through to production.
