subtracted. The particulate mass (Mf for the single filter method; Mf,i for the multiple filter method) is the sum of the particulate masses collected on the primary and back-up filters. If background correction is to be applied, the dilution air mass (MDIL) or volume (VDIL) through the filters and the particulate mass (Md) shall be recorded. If more than one measurement was made, the quotient Md/MDIL or Md/VDIL must be calculated for each single measurement and the values averaged.
