Tofwerk is a world-leading manufacturer dedicated to developing ultra-sensitive mass spectrometers to comprehensively characterize the composition and purity of samples. Researchers, industrial customers and state authorities around the world rely on their advanced technologies for discovery, compliance and decision making.

Vocus CI Series Time-of-Flight Mass Spectrometer
The Vocus CI Series Time-of-Flight Mass Spectrometer are high-resolution mass spectrometers designed for real-time and trace-level measurement of Volatile Organic Compounds (VOCs) and Volatile Inorganic Compounds (VICs) in both gas and particle phases using chemical ionization (CI) technology, with customizable ion-molecule reactors for versatile analysis.
Each instrument in the series allows users to switch between the Vocus PTR Reactor for general VOCs analysis and the Vocus AIM Reactor for optimizing detection for target analytes or adapting to evolving research needs. For enhanced separation, pair any instrument with the Ion Mobility Spectrometry (IMS) option for real-time isomer separation, setting a new standard in precision and performance.
Key Feature
Vocus PTR Series Time-of-Flight Mass Spectrometer
The Vocus PTR Series Time-of-Flight Mass Spectrometer are compact and economic mass spectrometers for real-time trace Volatile Organic Compounds (VOCs) monitoring and screening.
The Vocus PTR Series offers comprehensive VOCs coverage, particularly for hydrocarbons and oxidized organic compounds. These instruments are compact, durable, energy-efficient and require no external gases for operation, making them ideal for both field deployment and mobile applications in air toxics identification, source emissions characterization, fenceline monitoring and production-line quality control.
Key Feature
Vocus B Series Time-of-Flight Mass Spectrometer
The Vocus B Series Time-of-Flight Mass Spectrometer are bipolar mass spectrometers with millisecond reagent ion switching for comprehensive analysis based on simplified mass spectra.
The Vocus B series offers simplified mass spectra and customizable ion chemistries, enabling researchers to target a wide range of analytes. With fast polarity switching technology and VUV (Vacuum Ultraviolet)-based reagent ion generation, these instruments seamlessly switch between four reagent ions in only two seconds, providing real-time and fragmentation-free analysis. Combining the high sensitivity and soft ionization of the Vocus AIM Reactor with unparalleled compound coverage, the Vocus B series is an ideal solution for air quality studies, atmospheric chemistry and industrial research applications.
