M
f
= mass [ g] collected on
fine
particle fraction filter
M
c
= mass [ g] collected on
coarse
particle fraction filter
V
f
= volume [m³] of air sampled through
fine
particle fraction filter
V
c
= volume [m³] of air sampled through
coarse
particle fraction filter
V
t
= volume [m³] of air sampled through both
fine
and
coarse
particle
fraction filter (total volume)
Example: During a 24-hour sample run 2.4 m³ of air is sampled through the
coarse
fraction filter and 21.6 m³ of air is sampled through the
fine
fraction
filter. Laboratory
analysis (sample filter equilibration and subsequent
weighing on a microbalance)
determines that the mass collected on the
coarse
fraction filter is 768 g, while the
mass collected on the
fine
fraction filter is
846 g. What is the mass concentration of
fine
PM,
coarse
PM and PM
10
?
For
fine
PM (using equation 1):
For
coarse
PM (using equation 2):
For PM

(using equation 3):
To report volumes in standard terms, the user must ensure that the standard
temperature and standard pressure parameters in the Instrument Setup screen
are set to their proper values. In many countries, standard volumes are
defined in terms of 760 mmHg pressure and 25 °C temperature. Flow
volumes referenced internally by the Sampler to 0 °C are converted to
standard conditions using the following computation:
