The RF focusing fields in the Vocus ion molecule reactor improve sensitivity while maintaining product ion energies and recorded branching ratios that are nearly identical to those of traditional drift-tube PTR ion-molecule reactor designs.
The Vocus PTR-TOF offers unmatched sensitivity and mass resolving power for online detection of VOCs
A proton transfer reaction mass spectrometer (PTR-MS) with sub-ppt limits of detection and mass resolving power up to 15000
Announcing Improved Vocus PTR-TOF Performance and a New Model for Online VOC Monitoring
Advantages of the Vocus PTR-TOF
The Vocus PTR-TOF is a proton transfer reaction mass spectrometer (PTR-MS) for sensitive, real-time detection of volatile organic compounds (VOCs) in industrial, laboratory, and field applications.
- Ultra-Low Limits of Detection. High sensitivity and low backgrounds combine to yield sub-ppt VOC limits of detection in seconds
- Highest Available Mass Resolving Power. Mass resolving power up to 15000 enables identification of isobaric compounds in complex mixtures
- Mobile Measurement. Compact, durable architecture brings laboratory-grade performance to vehicle and aircraft-based measurements
- Adaptable for Your Applications. Work with us to integrate the Vocus PTR-TOF into your existing sampling systems and workflows
- Intuitive, Powerful Software. Easy-to-use data acquisition interface and Tofware graphical post-processing software for the analysis of high-resolution TOF data
- Revolutionary PTR Reaction Cell Design. The proprietary Vocus reaction cell reduces wall losses and focuses ions to give you up to 10x the sensitivity of other commercial PTR-MS. Learn more about the Vocus technology
Volatile organic compounds (VOCs) are ubiquitous chemicals that play a significant role in many systems, including health, the environment, food, and industry. Characterization of VOCs can be complicated because they are often trace constituents within complex mixtures. The Vocus PTR-TOF offers unprecedented performances for real-time identification and quantification of VOCs in all fields. The following examples illustrate the instrument’s key advantages.
