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
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:
