TOFWERK’s Vocus PTR Series provides comprehensive coverage for VOC monitoring, especially for hydrocarbons and oxidized organic compounds.
These instruments are compact, rugged, energy efficient, and require no external gases for operation, making them ideal for field or mobile applications.
Whether used for airborne toxics, source emissions, enclosure monitoring, or in-line quality control, the Vocus PTR Series offers sensitivity, low sample flow, and high versatility.
The Proton Transfer Reaction (PTR) reactor is a powerful system for analyzing a wide range of volatile organic compounds (VOCs).
The unique Vocus PTR reactor reduces wall losses and focuses ions with radio frequency (RF) fields to provide the highest sensitivity and low limits of detection.
Available with a variety of positive reagent ions for flexible VOC detection
High sensitivity with quantitative detection of VOCs from pptV to ppmV
No dependency on water vapor.
Applications:
-
Ethylene Oxide Monitoring: TOFWERK has developed a method using the Vocus PTR reactor in O₂+ adduct mode to detect EtO without interference from acetaldehyde or other compounds
- Fixed on-site monitoring
- Field monitoring of ambient air
- Fenceline monitoring.
TOFWERK AirTox Monitor technology provides a reliable solution for both field and fixed-site environmental monitoring, providing rapid, highly sensitive measurements without sample preparation.
