HTabsOverview The Aeroexplorer system: particulate and trace gas sampling measurements AirPhoton has developed a set of filter stations instruments for retrospective analysis of particulate matter. The Aeroexplorer sampling station comes in single and dual inlet models which allow for sequential or simultaneous collection of particulates at two size cuts between PM2.5 and PM10. In conjunction with the real-time measurements from our nephelometers, users can get a complete picture of particulates for air quality. Additionally, the Aeroexplorer sampling station is highly customizable, accommodating a wide range of research needs. The system components, such as controllers, pumps, inlet boxes, inlet heads, and cartridges, can be configured in various ways to suit specific sampling requirements. This flexibility ensures that users can optimize their setups for accurate and comprehensive particulate matter analysis. Recently, we have enhanced its capabilities with a new station designed specifically for trace gas measurements. This advanced instrument can measure a variety of gases, including ammonia, nitrates, and volatile organic compounds, each of which play a crucial role in air quality analysis. The instrument is composed by four denuders, which allows us to sample by wind direction. This allows for analysis of source apportionment or fence-line monitoring. This instrument operates at low flow rates which can be supported by solar or battery power so that the instrument can be deployed in remote and or environmentally sensitive areas. The Aeroexplorer sampling station: Single Inlet System The Aeroexplorer sampling station is a versatile instrument for collecting particulate matter on filters for later analysis. Particulates can be collected in two sizes, typically PM2.5 and PM10 on up to 8 filters on a user programmable scheduled. The instrument has data ports which can be used to communicate with external instruments such as a weather station to enable collection by wind direction or coordination with our nephelometers. The instruments permits an autonomous particle sampling. Pump turns on/off and sampling advances to next filter slot, automatically, as function of minutes, hours or days. All is directed by operator-initiated programs, input with intuitive button controls or script command uploads. The Aeroexplorer sampling station: Dual Inlet System The Dual Inlet configuration of the sampling station allows for simultaneous collection of particles at two different sizes depending on the choice of inlet size. Shown at right is the instrument configured with two cyclone inlets. The system can also be configured to use mini-impactors for the collection of larger-sized particles. This adaptability ensures precise sampling tailored to diverse research requirements.
