Gas Phase instruments
Technologies designed by Aerodyne scientists to pursue the advancement of our understanding of the changing environment.
Gas Phase Instruments
A wide array of Mass Spectrometric based instruments for real-time aerosol size and chemistry, optical particle instruments for aerosol extinction and single scattering albedo measurements. This array of products includes research grade instruments as well as smaller monitoring-based instruments.
TILDAS Trace Gas Analyzer
The TILDAS Compact Single Laser Trace Gas Analyzer is a compact, single laser trace gas analyzer. It is our smallest and most economical laser trace gas instrument. The instrument can be configured to detect many trace gas species including NO, N2O, NO2, NH3, CO, CO2, CH4, C2H6, COS, HCHO, O3, EtO and many others.
The TILDAS Dual Laser Trace Gas Analyzer enables the simultaneous measurement of multiple species using two multiplexed lasers. Many different molecules can be measured with TILDAS, but only a small subset of that list can be monitored with any specific pair of lasers. Typically, each laser can measure one to three molecular species. Depending on which lasers are selected, a dual laser analyzer can detect between two to six molecular species. There are hundreds of possible combinations so it is not feasible to list all the possibilities.
These instruments rely on rapid sweep Tunable Infrared Laser Direct Absorption Spectroscopy (TILDAS) implemented with long path Astigmatic Mult-pass Absorption Cells (AMAC)

Gas Chromatograph
Aerodyne Research offers a modular gas chromatograph (GC) with thermal desorption preconcentration (TDPC) that combines recent innovations in fast GC separation with highly selective and sensitive detection in a field-deployable package for the measurement of VOCs and OVOCs.
Aerodyne works with our customers to provide a GC system with a custom separation method appropriate for their analytical needs. The instrument delivers with the required capillary column installed and analytical methods pre-loaded into the Windows-based control software, for a true turn-key operation.
Potential Aerosol Mass Oxidation Flow Reactor
The PAM-OFR provides a highly oxidizing environment that simulates oxidation processes on the timescales of day in the atmosphere in minutes in real time.
