  skos: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 ;
