Particle Size convention

Particle Size convention

LCS Laboratory is proud to be the only commercial laboratory (as per 2016) in North America that offers size selective sampling for thoracic dust. The World Health Organisation defines  thoracic dust as “that fraction that can penetrate the head airways and enter the airways of the lung”. According to the International Convention the thoracic fraction of dust has mass median diameter of 10 micron. Particle size of Thoracic dust is smaller than in Inhalable fraction, but twice larger than of Respirable dust. In Ontario, Canada, only 2 materials are regulated as Thoracic dust (2103): Cotton and Sulfuric Acid.

Our laboratory offers air sampling cyclones for thoracic dust, sampling pumps, sampling cassettes  for all your sampling needs. Please email us to order your sampling kit or to discuss your project
