Bring the lab anywhere.
Real-time measurement of trace compounds in air
Real-Time Chemical Ionization Mass Spectrometers
Instantaneous Analysis
Directly sample air to quantify, characterize, and report volatile organic and inorganic compounds (VOCs and VICs) in complex mixtures in real-time, without chromatography.
Unmatched Performance
Vocus delivers sub-ppt limits of detection for a diverse range of compound classes.
Built for Exploration
Laboratory performance that goes anywhere. A rugged, compact design means that your instrument goes where your sample is, not the other way around.
