MACS
Definition
- Multiple Aerosol Collection System (MACS) contains an impactor collector, which permits the collection of particles on electron microscope grids for later chemical-constituent analysis. The collector consists of a two stages. In the first stage the pressure of the sample is reduced by a factor of two without loosing particles by impaction on walls. The second stage consists of a thin plate impactor which collects efficiently even at small Reynolds numbers. The system collects particles as small as 0.02 micron at WB-57F cruise altitudes. As many as 24 samples can be collected in a flight. (en)
