The online sampling solution consists of a Multi-scheme chemical ionization inlet, MION2, and a mass spectrometer (MS). MION2 employs soft ionization to generate reagent ions, which are then clustered with a sample gas. Thanks to its design features and operation at ambient pressure, MION2 contributes to achieving excellent detection limits. To facilitate the analysis of a broader range of compounds, MION2 allows for fast switching between sources with different reagent ions.
MION2Offline sampling includes the utilization of a Thermal Desorption Unit, chemical ionization of a sample in MION2, and subsequent detection of compounds in a mass spectrometer. Tenax-coated mesh filters are employed to enhance vapor or aerosol particle retention during the collection of air samples. The large adsorption surface area contributes to fast sampling and higher collection efficiency. Reusable cassettes allow easy filter replacement while contributing to cost-efficiency.
