Dust Sampling - Inhalable
For inhalable dust the I.O.M. Sampler is used.
The filter is placed between the cassette front
and the support grid, which clip together to
make a one piece unit. The
whole cassette
assembly is then pre-weighed before a
sample is taken. After completion of the
sample the
whole cassette assembly is
then post-weighed.
The I.O.M. Sampler retains all the particluate
drawn into it using this filter/cassette
combination, and eliminates problems of wall
loss, whereby some of the particulate adheres
to the walls of the sampler, and the resulting
potential for under sampling, as experienced
with other types of sampling device.
