Gas Phase Monitors Overview:

Laser Trace Gas and Isotope Analyzers

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.

Vocus Chemical Ionization Mass Spectrometer

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

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 PM_ex and PM_SSA monitors measure particle optical properties.

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.

Field-Deployable GC for TOF-MS

Aerodyne Research, Inc. (ARI) offers a modular gas chromatograph (GC) 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 (PAM) Oxidation Flow Reactor

A highly oxidizing environment that simulates oxidation processes on timescales of days in the atmospherein minutes in real time.
