TOFWERK is proud to present the Vocus High Resolution (HR) mass spectrometer, offering the best mass resolving power of any commercially available online chemical ionization time-of-flight mass spectrometer.
With a remarkable resolution of 30,000 M/ΔM, the Vocus HR sets new benchmarks for analytical performance while preserving the reliable architecture and field-deployable design that researchers have been accustomed to from the Vocus product family.
The Vocus product line has developed itself as the preferred technology for real-time VOC and VIC measurement, continuously tackling the increasingly difficult analytical challenges confronting researchers in the atmospheric, environmental, and broader scientific domains.
With the Vocus HR, researchers can identify even the most difficult isobaric interferences in real time, whether working in remote field locations or complex laboratory settings. This marks a significant advancement in high-performance real-time chemical ionization mass spectrometry as well as an expansion of the Vocus product line.
Unparalleled Flexibility and Performance
With its remarkable design and versatility, the Vocus HR redefines analytical capabilities. Researchers can now use multiple well-characterized ion chemistries, add ion mobility spectrometry (IMS), replace powerful PTR and Aim Reactors, and incorporate an online particle measurement option.
This all-encompassing approach guarantees a versatile instrument to meet the most demanding analytical challenges and adjust to changing research needs.

Unprecedented Analytical Insights
Outstanding analytical skills are made possible by the 5.5-meter flight path, which exhibits exceptional performance in several crucial research domains:
- Distinguishing difficult isobaric interferences
- In-depth examination of organonitrates and peroxy radicals
- Accurate characterization of sulfur-containing compounds
- Unprecedented insights into atmospheric chemical processes
The figure below displays Vocus HR’s outstanding separation capabilities.

The Vocus HR distinguishes between peroxy radicals and organic nitrate compounds in the left panel. This separation sheds light on volatile organic compound oxidation processes that influence ozone generation, particulate matter development, and environmental and health consequences.
The right panel illustrates the Vocus HR's capacity to identify sulfur-containing compounds from surrounding closed-shell products, which is otherwise a tough task with lesser-resolution instruments. This capability provides vital information regarding atmospheric chemistry and particle formation mechanisms, influencing climate dynamics and human health outcomes.
These examples demonstrate how the Vocus HR’s improved resolution converts previously indistinguishable signals into clearly differentiated peaks, allowing researchers to define complicated chemical processes with unprecedented clarity.
Field-Deployable Excellence
The Vocus HR is designed for optimum dependability and convenience and establishes new standards for field deployability. Some of the key benefits include:
- Reduced power usage compared to competing models
- Minimum temperature sensitivity and humidity independence
- Compatibility with nitrogen generators, reducing the requirement for complex gas cylinder logistics
- Sturdy, small frame that can support measurements in remote and lab settings
Whether doing sophisticated atmospheric research, examining climate consequences, or investigating human health interactions, the Vocus HR provides researchers with an unrivalled toolkit for making groundbreaking scientific findings.
