Webinar: Direct, Real-Time Measurement of Inorganic Acids, Organics, and PFAS in Air Using the Vocus Aim Reactor

Vocus Aim Reactor Webinar

Soft chemical ionization (CI) coupled with TOF mass spectrometry is a powerful technique that allows real-time, direct measurement of trace compounds for air or headspace analysis. TOFWERK’s unique Vocus Aim Reactor is a medium-pressure flow tube CI reaction cell that is optimized for adduct-ion and charge-transfer ionization to analyze diverse compounds, including inorganic acids, VOCs, and PFAS.

In this webinar, we review key advances enabled by the Vocus Aim Reactor, with comparison to other chemical ionization approaches, such as proton-transfer-reaction (PTR).
