To ensure people’s safety and a good repeatability of industrial process, the analysis of ambient air is crucial. Electronic boards are produced in clean air room by complex lithographic process using very reactive chemicals. The nature and concentration of volatile compounds can be different depending on the chemical process and can also vary rapidly. There is a need to analyze precisely and continuously gas process in air with an instrument designed for industrial use.
Since 1986, Chromatotec® is a worldwide recognised expert in gas analysis, renowned and certified for its precise analysis in ambient air monitoring and natural gas. In industry, Chromatotec’s systems prove their value in online monitoring, quality control and environmental protection. They make substantial contributions to process control, to the improvement of product quality, and to the enhancement of system safety as well as to environmental protection. Chromatotec® has developed a turnkey solution which allows the quantification and identification of compounds at ppt, ppb, ppm and % levels. The airmoTWA is a new industry standard for online and continuous TRAP/GC/MS/FID. It encompasses a specific trap to concentrate the sample, a column for separation of chemicals and two detectors : a new micro flame ionization detector (FID) and a mass spectrometer for quantification and identification respectively.
The airmoTWA is simple to use and incredibly sensitive and delivers robust and reliable performance. Particularly, the instrument can monitor and record a large number of concentrations of molecules and can have alarm systems which can be set to inform on important changes of the surrounding atmosphere.
In the Figure 1, a mass spectrometer chromatogram obtained analyzing ambient air is shown. The peak resolution and sensitivity of the instrument allows quantifying and identifying very low VOC concentrations.
