Regulators and consumers demand increasingly lower levels of harmful volatile emissions in motor vehicle passenger cabins, pushing manufacturers toward more comprehensive testing — from raw materials to components to finished vehicles — to ensure conformance and avoid costly tear-out. However, conventional analytical technologies are expensive, complex, and slow, since they are based on chromatographic methods.
Selected ion flow tube mass spectrometry (SIFT-MS) is an innovative, industry-proven analytical technique that directly and instantly analyses air down to part-per-trillion (ppt) concentrations, providing rapid component screening and immediate process feedback. SIFT-MS selectively and quantitatively analyzes the complete range of emitted volatile organic compounds (VOCs; e.g. formaldehyde, acrolein, benzene, styrene, and dichlorobenzene) and inorganic gases (e.g. ammonia).
This webinar introduced SIFT-MS and outlined the benefits that make it the ideal tool for product emission testing applications. Dr Holzwarth presented examples that illustrate how SIFT-MS has been applied to a range of emissions testing applications in the imat-uve laboratory. imat-uve evaluations included comparative studies that parallel the ISO 12219-4 emission testing chamber standard.
