In January 2023, TOFWERK supplied the Colorado Department of Public Health and Environment (CDPHE) with a mobile laboratory. TOFWERK has also assembled and operated comparable mobile monitoring facilities worldwide, including locations in China and Europe.
The unparalleled capabilities of Vocus mass spectrometers make them the ideal solution for various air measurement applications. In terms of both performance and the compact footprint of the units, Vocus is being increasingly praised for its use in mobile lab applications.
Features
- Robust, responsive, rapid, mobile analysis of trace gases that covers both VOCs and VICs
- Uninterrupted operation supported by a self-sufficient power system
- Numerous sensors seamlessly integrated into a universal data flow
- Complete mobile workspace for on-site operations, including a cockpit, workstation, gas cylinder storage, tools, and cabinets
Scientists and regulators using Vocus mobile air monitoring labs can be safe knowing they are adequately prepared for emissions monitoring campaigns.
Conventional fenceline monitoring systems have work to do to match Vocus systems' speed, sensitivity, and measuring capabilities. With heightened sensitivity and rapid capture, Vocus measures an extensive range of VOCs and VICs in the field in real time.
It traces known hazardous compounds while measuring thousands of other compounds, several of which can pose health risks and other hazards. Specialized software simplifies data merging from the different sensors into a single visual representation and data file.
