Our main products are state of the art scientific instruments.  Most of these instruments are designed to measure gases or aerosol particles in real time and with great sensitivity.  We also produce a variety of technical software products.


Aerosol Mass Spectrometers

Aerodyne produces a wide variety of mass spectrometric instruments to study or monitor particulate matter.  These instruments are capable of revealing both chemical composition and particle size.  These include research instruments with extremely high mass resolution as well as more affordable monitoring instruments.


Chemical Ionization Mass Spectrometers

Aerodyne sells two types of CIMS instruments.  The first is the gas phase version which detects molecular species with extraordinary sensitivity. The second is the MOVI-CI-TOFMS which monitors the chemical composition of particulate matter.

Laser Trace Gas Monitors

We produce a variety of trace gas monitors that detect gas phase molecules using Tunable Infrared Laser Differential Absorption Spectroscopy (TILDAS) with quantum cascade (QC) lasers.  These monitors have fast time response (up to 10 Hz) and extremely high sensitivity.  Applications include greenhouse gas monitoring, pollution monitoring and isotopic monitoring.

CAPS Particle and NO2 Monitors

Aerodyne offers three instruments based on the principle of Cavity Attenuation Phase Shift (CAPS) detection.  These instruments provide state-of-the-art sensitivity at low cost.are low cost.   The CAPS NO2 monitor provides sub-100 parts-per-trillion precision in 10 s.  The CAPS PMex and PMSSA monitors measure particle optical properties.

Technical Software

Aerodyne Research has created powerful software tools for analyzing large complex data sets using the High Dimensional Model Representation.

We also develop and maintain codes for predicting EO/IR signatures from the ultraviolet to the infrared.



The new VOCUS-PTR instrument delivers ultra-low limits of detection with the highest available PTR-MS mass resolving power in a field-proven API-TOF platform.
