Real-time measurement of trace compounds in air
Vocus CI Series
The Vocus CI Series are high performance, field-ready mass spectrometers for real-time trace detection of a broad range of compounds. With drawer-like modules, automatic connections, interchangeable accessories, and integrated tools, these carefully engineered instruments feature a compact footprint optimized for both laboratory and field measurements.
Switch between the VUV-based Vocus PTR Reactor for general VOC analysis and the highly sensitive, selective Vocus Aim Reactor, optimizing detection for target analytes or adapting to evolving research needs.
- Fast, real-time analysis with sub-pptv limits of detection
- High specificity with high mass resolving power
- Compact, field-ready design

Wintertime Ambient Air Measurements of Trace Inorganics
Data collected from a Vocus 2R CI-TOF equipped with a Vocus Aim Reactor operating in I- mode to measure volatile inorganic compounds in ambient air over a 15-day wintertime period in Thun, Switzerland. This demonstrates the unique ability of the powerful CI-TOF coupled with the Vocus Aim Reactor to measure inorganics in ambient air at concentrations ranging from ppqv to ppb.

Vocus Flex 2R Mobile Deployment
The compact size of the high-performance Vocus Flex 2R CI-TOF (approximately 1 meter tall) enables exceptionally accurate, real-time measurements in conventional-sized vehicles. The timeseries shown here demonstrates mobile measurements conducted in Thun, Switzerland, using a Vocus PTR Reactor in a hybrid-electric SUV. This data shows high-precision measurements at low ppt concentrations with one-second time resolution. Read more about this study here.
