Dust Analysis
  • Gravimetrical dust analysis
  • By this method a known amount of air is fed to a filter. The dust in the air is trapped with an efficiency > 99%. The total dust particles are the sum of the respiratory and thoral fractions.
  • Iso-kinetic dust analysis (dust-emissions)
  • During sampling the linear velocity of the sampling gas in the the sample-probe is equal to the linear velocity of the main stream.
  • Optical dust monitoring
  • With the on-site dust monitor the particles in the air are measured directly. The technique is based on the reflection of infra red light.
    Calibration and validation can performed for all methods.
