gravimetric particle size equipment

  • Dekati - Model DGI - Gravimetric Impactor

    DGI-1570 (Dekati® Gravimetric Impactor) is a high sample flow rate cascade impactor designed for measuring gravimetric particle size distribution of particles < 2.5 µm. In a standard DGI setup particles are size classified into 5 size fractions with impactor stage cutpoints of 2.5, 1.0, 0.5 and 0.2 µm. If detailed information on ...

  • Dekati - Model DLPI+ - Low Pressure Impactor

    DLPI+ (Dekati® Low Pressure Impactor) is a 14-stage cascade impactor to measure airborne particle mass size distribution. The DLPI+ classifies particles into 14 size fractions in the range of 16nm-10µm. In each size fraction the particles are collected on 25 mm collection substrates that are weighed before and after the measurement to ...

  • Wide Range Aerosol Spectrometer

    Gravimetric measurements have shown that the entire part of the mass of fine dust below 0.5 µm makes up less than 1%. But if the particles are counted, 80% below the size range of 0.5µm. It is not obvious if the particle number or the particle mass has a greater effect on the human health. Therefore it would be useful to have a device ...

  • Filter-Check SubMicron Aerosol Spectrometer/Filter Efficiency Monitor

    The requirement for filter efficiency measurement (contamination control) has been outlined for years by ASHRAE 52.1 as a classical gravimetric method. Since the concentration of smaller particulate in ambient air is dramatically increasing, new methods need to be developed for air cleaning devices to study the removal efficiency by particle size. ...

  • Dekati - Model PM10 - Impactor

    Dekati® PM10 impactor is a three stage cascade impactor for determining particle gravimetric mass size distribution. This impactor has cutpoints of 10, 2.5 and 1 µm and if needed some of the stages can be removed from the assembly to make a simpler setup. The Dekati® PM10 impactor is an ideal choice for applications where some ...
