AIRPHOTON / GRASP Earth. products

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 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.

The AirPhoton 8-slot filter cartridge is a unique design that holds and protects 8 particle sampling filters. This design minimizes the handling of the filters in the field and reduces the frequency of site visits by technicians. Used in conjunction with the AirPhoton Explorer Automated Filter Sampling Station, the cartridge can be deployed through 8 sampling cycles (one of which can be a blank for reference) before exchange with a fresh cartridge is necessary. Each of the 8 slots can hold either 1 filter for straightforward measurements of particles of one size, or 2 sequential filters of different pore sizes for separation of particles by size. When used with the dual inlet system and control box each inlet can be used separately for four sampling cycles. One filter location for each flow can be used as a reference blank.
