In January 2023, TOFWERK provided a mobile laboratory to the Colorado Department of Public Health and Environment (CDPHE). In addition to this laboratory, TOFWERK has also constructed and deployed comparable fenceline monitoring laboratories worldwide, including in China and Europe.

The Vocus mass spectrometers excel in trace gas measurements, rendering them the ideal solution for a wide spectrum of air measurement needs. Due to its performance and compact size, Vocus is rapidly gaining prominence in mobile laboratory applications.
Features
- Sturdy, sensitive, swift, mobile trace gas analysis covering VOCs and VICs
- Independent power system for uninterrupted operation without relying on shore power
- Incorporation of various sensors into a universal data flow
- Comprehensive workspace for on-site activities, encompassing a cockpit, workstation, gas cylinder storage, tools, and cabinets
By using Vocus mobile air monitoring laboratories, regulators and researchers can ensure they possess adequate equipment for emissions monitoring campaigns.

Most traditional fenceline monitoring systems fall short when it comes to the speed, sensitivity, and range of compounds they are capable of measuring. However, with its rapid speed and heightened sensitivity, the Vocus can measure a broad array of VOCs and VICs.
The Vocus monitors known hazardous compounds in real-time while concurrently tracking thousands of other compounds, many of which are also hazardous. The software efficiently organizes data from multiple sensors into a unified visualization and data file.
