For respirable dust a Cyclone Sampler can
be used, which separates the respirable
fraction (approximately 12 micron and below)
of the particlulate from the atmosphere drawn
through it. The Cyclone Sampler is designed
so that smaller particles are carried onto the
filter paper inside the cassette and larger
unwanted particles drop into the grit pot.
Unlike the IOM Sampler cassette/filter paper
combination, the Cyclone version should not
be weighed as a unit. Only the filter paper is
weighed pre and post sampling.
This instrument must be run at a flow of 2.2 litres
per minute to give the correct performance.
