The ease of use, sensitivity, selectivity, and high-throughput analysis provided by Syft Technologies’ Voice200ultra SIFT-MS solution provides simple, reliable, and economic analysis of vehicle interior air quality on the production line and in the parking lot.
The high-speed, sensitive analysis provided by SIFT-MS makes it ideally suited to testing of chemically diverse VOCs for vehicle interior air quality. SIFT-MS eliminates expensive sampling consumables, sample preparation prior to analysis, and delays arising from laboratory-based analysis. Syft Technologies’ instruments are also extremely easy to use and are designed for industrial applications. Combined, these benefits provide instant feedback on the acceptability of every vehicle coming off the production line.
Public concerns about the health impacts of the “new car smell” have led several countries to impose limits on permissible concentrations of certain volatile organic compounds (VOCs). For example, on 1 March 2012, the Chinese government issued a standard to regulate the vehicle interior air quality (VIAQ) of new vehicles. Details of the Chinese, Japanese, and Korean standards are shown in Table 1. Currently these standards are based around two traditional laboratory-based analytical methods (gas chromatography mass spectrometry (GC/MS) and high- performance liquid chromatography (HPLC)) that are expensive, have slow sample turnaround, require trained laboratory technicians, and are incompatible with rapid testing on the production line or in the parking lot.
|Compound||Maximum permissible concentrations / μg m-3||LOD / μg m-3|
Syft Technologies’ Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) solution provides a very attractive alternative to the GC/MS- and HPLC-based methods. In one simple, rapid analysis, all aldehydes and other VOCs required by the Chinese, Japanese, and Korean standards are detected and quantified. The unique ability of SIFT-MS to simultaneously analyze the small, reactive aldehydes and general VOCs in real time arises from the use of ultra-soft ionization and the elimination of chromatographic separation. Example results for three new vehicles from the same manufacturer are shown in Figure 1.
Moreover, since SIFT-MS provides ease of use, simple reporting and is a robust, direct analysis technique that requires no sample preparation or preconcentration, it can be used to economically screen all cars coming off the production line. This ensures that any deviations from the standard production specification can be identified immediately, allowing corrective actions to be taken.
