Aerosol Chemical Speciation Monitor

The Aerodyne Aerosol Chemical Speciation Monitor (ACSM) measures quantitative particle mass loading and chemical composition in real-time for non-refractory sub-micron aerosol particles.   Smaller, lower cost and more robust than our AMS instruments, the ACSM is designed for long-term unattended deployment and routine monitoring applications.
Unlike the AMS, the ACSM does not provide size resolved composotion information.

ACSM Applications
  • Measurement of aerosol mass loadings and chemical composition with >15 minute time resolution for routine environmental monitoring.
  • Routinely reports average particle NO3, SO4, NH4, Cl and Organic fraction.
  • Advanced analysis provides separation and quantification of organic aerosol species including HOA (hydrocarbon-like organic aerosol, linked to primary combustion sources) and OOA (oxygenated organic aerosol, linked to secondary aersol sources) using numerical deconvolution methods (e.g., Positive Matrix Factorization)
  • Deployment on mobile platforms, such as vans.
  • Chamber studies of aerosol formation and processing.
  • Industrial process monitoring.
CO2 Isotope Trace Gas Monitor

A Novel Dual Cell gas analysis system for continuous, accurate, simultaneous measurement of concentrations of Carbon Dioxide isotopologues.

A room temperature continuous wave QCL laser from Alpes Lasers, is operated in the 2310 to 2315 cm-1 range to obtain simultaneous detection of 13CO2 and C18OO and  12CO2.

Applications
  • Atmospheric monitoring of isotopic gradients from aircraft and other mobile platforms
  • Eddy covariance iso-flux measurements
  • Isotopic composition measurement
Aerosol Mass Spectrometer
  

The Aerodyne aerosol mass spectrometer (AMS) is the only currently available instrument capable of providing quantitative size and chemical mass loading information in real-time for non-refractory sub-micron aerosol particles. The AMS couples size-resolved particle sampling and mass spectrometric techniques into a single real-time measurement system. The Aerodyne AMS has been deployed world-wide at fixed sites, and on mobile laboratory, ship and aircraft platforms. Over 100 instruments are in use in industrial, academic and government laboratories.

Applications

  • Measurement of ambient atmospheric aerosol mass loadings and size distributions for environmental monitoring.
  • Emissions characterization of combustion sources. Direct determination of OC emissions indices with simultaneous measurement of plume CO2.
  • Eddy correlation flux measurements of aerosol sulfate, nitrate, ammonium, and organic species dry deposition fluxes.
  • High time-resolution mapping of fine aerosol properties from affordable mobile (van, small aircraft) platforms.
  • Diagnostic for laboratory aerosol sources, flow reactors or aerosol chambers for aerosol physics and chemistry experiments.
  • Analysis of chemical composition as a function of particle size for aerosol delivery systems such as metered dose inhalers.  High time-resolution allows measurements on a puff-by-puff basis, eliminating need for time-consuming impactor analyses.
  • Single particle chemical analysis with light scattering module and time-of-flight mass spectrometer.
Quantum Cascade Laser Mini Monitor

 

Sensitive, rapid, highly specific and continuous measurements of atmospheric trace gases in ambient air. See the world's most precise nitrous oxide (N2O) monitors.

Applications
  • Detection of a wide variety of atmospheric trace gases, such as: methane, nitrous oxide, nitric oxide, nitrogen dioxide, carbon monoxide, carbon dioxide, formaldehyde, formic acid, ethylene, acetylene, carbonyl sulfide, acrolein, ammonia and others.
  • Isotopic monitoring of CO2, CH4, and N2O.
  • Combustion monitoring and characterization.
  • Isotopic monitoring for source/sink characterization.
  • Eddy Covariance measurements for nitrous oxide and other trace gases.
  • Fast response plume studies.
  • Breath analysis.
  • Air quality monitoring.
  • Mobile measurements from ship, truck, and aircraft platforms.
  •  Simultaneous monitoring of N2O, CO2 (or CO) and water vapor with unprecedented precision.
Thermal Desorption Aerosol Gas Chromatograph AMS (TAG-AMS)
The TAG-AMS project is a collaborative development between ARI, Professor Allen Goldstein at UC Berkley and Dr. Susanne Hering at Aerosol Dynamics, Inc.
The TAG-AMS combines the advantages of the Aerodyne High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) (Canagaratna et al, Mass. Spec. Rev., 26, 185-222, 2007) measuring size distribution and mass loading for ambient aerosol and the Thermal desorption Aerosol Gas Chromatograph (TAG) (Williams et al., AST, 40, 627-638, 2006) instrument providing hourly measurements of speciated organic compounds.  The combined TAG-AMS instrument shares the same electron impact ion source and HR-Tof-MS for analysis of the atmospheric aerosol constituents.  
Chemical Ionization Mass Spectrometers

 

Aerodyne offers chemical ionization mass spectrometer systems that provide highly sensitive and highly selective detection of gas- and particle-phase organic species.  Chemical ionization is a soft ionization technique that enables molecular identification.

The Chemical Ionization Mass Spectrometer (CIMS) Trace Gas Monitorcombines a chemical ionization source with a high-resolution time-of-flight mass spectrometer for quantitative detection of specific chemical classes in the gas-phase.

The Micro-Orifice Volatilization Impactor Chemical Ionization Time of Flight Mass Spectrometer (MOVI-CI-TOFMS) combines the CI-TOFMS with the unique Micro-Orifice Volatilization Impactor (MOVI) inlet that allows measurement of both particle-phase and gas-phase compounds.
