MFS
Multi-Filter Sampler

The Multi-Filter Sampler (MFS) is an airborne system designed to collect aerosols and gases on a filter medium. It collects air samples by inserting and removing filters from the airstream as directed by the pilot. It also records parameters such as air temperature, pressure, flow rate, and instrument diagnostics. After the flight, the filters are extracted using an aqueous solution, which is then analyzed through ion chromatography to identify the aerosols and gases. The MFS has an accuracy of approximately 20%.
