Real-time measurement of trace volatile organic and inorganic compounds in air
Vocus chemical ionization mass spectrometers deliver sub-ppt limits of detection for the measurement of VOCs and VICs, optimized for use in laboratories, industrial sites, and mobile applications
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.
Features
A comprehensive toolbox to address the needs of researchers and industry.
- Real-Time Measurements Report concentrations of volatile organic and inorganic compounds (VOCs and VICs) instantaneously.
- Interchangeable Reactors Increase the range and diversity of detectable compounds by interchanging the PTR and Aim Reactors. Let your instrument grow with your research or measurement goals adding multiple reactors at the time of purchase, or upgrade later as research directions shift.
- Fast Polarity Switching Polarity switching in milliseconds enables both positive and negative ion chemistries in one compact instrument. Particularly useful in combination with fast reagent ion switching. Learn More
- High Resolution Separation Separate isobars to enable confident, robust analysis of complex mixtures.
- Fast Reagent Ion Switching Reagent ion switching enables real-time monitoring using different reagent ions with a single reactor. Switching timescales are 50-100 ms for the Aim Reactor and as fast as 10 s for the PTR Reactor.
- Magnification Interface Transfer ions from the Vocus reactor to the TOF analyzer with the highest possible efficiency for improved sensitivity.
- VUV Reagent Ion Source A bright, safe, and robust ion source for the generation of a variety of reagent ions used in the Vocus Aim.
- Ion Mobility Mass Spectrometry Real-time monitoring of isomer populations with ion mobility mass spectrometry. Learn More
