    The primary factory reference method consists of generating a dust aerosol by means of a fluidized bed generator, and injecting continuously the dust into a mixing chamber from which samples are extracted concurrently by two reference filter collectors and by two master real-time monitors (Thermo Electron DataRAM 4) that are used for the routine calibration of every personalDataRAM.

  • Page 42: Scattering Coefficient Calibration

    The duration of this comparison run should be sufficient to collect a mass of at least 1 mg on the reference filter (in order to permit accurate weighing of the collected mass by means of an analytical balance). The time-weighted average (TWA) reading of the personalDataRAM can be used to estimate the required sampling time to collect the above-mentioned mass on the filter.
