A flexible, field-deployable gas probe array for monitoring biogeochemical changes in ecological and agricultural research. Spatiotemporal mapping of subsurface trace gases (including isotopes) and volatile organic compounds provides valuable insights into biogeochemical cycling, but very few methods measure in-situ soil gases. The Aerodyne Gas Sampling System includes our multi-sample selector (MSS), soil probes and must be used in conjunction with an array of instruments depending on the measurements needed. These include our TILDAS instruments, the Vocus CI-TOF, and the Vocus CI-TOF with our Gas Chromatograph. The Aerodyne Field Enclosure can also be added to conduct year-round measurements (fits TILDAS instruments.) Non disruptive soil probes collect gas samples via diffusion. Gas sample is transferred to the Multi Sample Selector (MSS) which uses multiport selector valves to connect a single analyzer to up to 16 probes! Samples are sent from the MSS to either a TILDAS or Vocus CI-TOF, depending on the desired measurements.

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 Multi-pass Absorption Cells (AMAC).

A highly oxidizing environment that simulates oxidation processes on timescales of days in the atmosphere in minutes in real time. Single, Dual and Triple Versions Available Available in single, dual and triple versions. The Potential Aerosol Mass (PAM) is an Oxidation Flow Reactor (OFR) that provides a highly oxidizing environment that simulates atmospheric oxidation processes on timescales ranging from a day to several days in a few minutes in the laboratory / field. In addition to being used as a source of secondary organic aerosol (SOA) particles, the PAM reactor is also used to simulate atmospheric processing of soot and other model primary organic aerosols. - Field deployable - Oxidants: O 3, OH, NO 3, Cl, Br - Wide range of oxidant exposure times attainable with dimmable UVC, UVB or UVA at high measurement throughput/resolution - Oxidant concentrations are 100 to 10,000 times larger than in the daytime troposphere, simulating days of atmospheric oxidation in minutes

A weatherproof, thermally stabilized instrument enclosure that provides a plug-and-play solution to deploy state-of-the-art instrumentation in the field. Aerodyne Field Enclosures are rugged, have a corrosion-free design and are field-ready. They are ideal for long-term deployment at remote sites with limited infrastructure. The enclosure provides very high temperature stability to ensure the lowest drift for internal instrumentation. They are ideal for measurements that require advanced thermal management. - Turn-key design allows unattended operation - Minimal perturbation on site wind flow - Weatherproof design: IP54 enclosure with IP67 electrical connectors - Wide ambient temperature range: –20 ˚C to +40 ˚C - Ideal for TILDAS trace gas monitors - Internal valve system: handles gas flow (optional). - Internal Nafion dryer: removes H 2 O from sample gas (optional). - Internal circulation scrubber: removes H 2 O to avoid condensation in humid areas (optional)
