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.

Gas Phase Monitors Overview:

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.

Vocus-PTR

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.

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.

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.

Fast-GC for TOFMS

The Fast-GC system is lightweight, compact and customizable with standard capillary colums up to 60-m in length. The column oven enclosure size is only 6.7″ x 6.7″ x 4.6″ (168 x 168 x 116 mm) with aluminum construction. Compatible with Electron Impact, VOCUS PTR and Chemical ionization sources. The sample interface uses two 2-position chromatography valves to direct sample flow to or bypassing sample loop, and to select direct sample flow or GC eluent to TOFMS detector. The user is able to select the sample loop size and material as needed to match the specific application.
