Custom TOF Case Studies

TOFWERK’s several successful collaborations are based on the blend of its mass spectrometry expertise with its partners’ knowledge of specific research domains and applications.

OEM Partner — Aerodyne Research

Aerodyne Research (Billerica, MA, USA) is a renowned center for online analysis of atmospheric gases and aerosols. Their research team and their wide network of customers use Aerodyne instruments to solve tough questions related to air quality and climate change — in the field, in the laboratory, and onboard mobile research platforms.

TOFWERK has provided TOF hardware and software to Aerodyne for over ten years, starting with the Aerodyne ToF Aerosol Mass Spectrometer (ToF-AMS), which combines Aerodyne’s aerosol sampling and sizing technology with a TOF mass analyzer. The ToF-AMS has become a basic component on all leading atmospheric research campaigns, and ToF-AMS data has been added into nearly 1000 publications. Aerodyne’s atmospheric product series currently includes versions of the Vocus PTR-TOF, IMS-TOF, API-TOF, and EI-TOF that have been modified and expanded to meet exceptional demands of atmospheric science.

Through its support of Aerodyne and their customers, TOFWERK has established expertise in the design of field deployable mass spectrometers. The challenging physical demands of atmospheric field work have boosted a strong standard for all TOFWERK hardware and driven the development of a number of components and features.

OEM Partner — Karsa

Karsa designs cutting-edge MS systems and accessories for molecular uncovering of explosives. Karsa, established in 2016, is a spin-off of the University of Helsinki. The TOFWERK and Karsa research teams have had a long and productive relationship, growing from the developments of new Atmospheric Pressure Chemical Ionization (APCI) techniques for atmospheric study at the University of Helsinki.

This APCI technology is extensively employed with the API-TOF for online, trace detection of gas-phase organic compounds, and is documented for having accomplished the lowest ever limit of detection for sulfuric acid. At present, TOFWERK and Karsa are working together to extend the use of interrelated technology for security applications and to enhance software and hardware for workflows and securities environments.

The Karsa ionization inlet can detect a broad range of chemical compounds at very low concentrations. The design realizes very high ionization efficiencies grounded on a high rate of reagent-analyte collisions. Soft ionization enables discovery of intact compounds rather than fragments, thus simplifying spectral interpretation and boosting confidence in the outcome. Karsa has also built equipment for both direct air sampling and capturing of particles and vapors on a filter media that is desorbed and examined later.
