How it works
The Digitel High Volume Sampler Single Filter Unit (DH-77) is a system to sample dust and aerosol particles for later assessment and analysis. The sampler operation range in standard execution is 100 to 1000 litres per minute (6 to 60 cubic metres per hour). The system’s usual designation is ‘High Volume Sampler’. Air-borne-dust parts in the sampled air are separated onto 150 mm diameter filters.
The flown filter diameter is 140 mm. Subsequent gravimetric and analytical analysis could be conducted then depending upon the pollutants of interest. Filter material and structure selection (deep filters, porous filters, glass fibres, silica fibres, pulp, Teflon, porosity….) will depend on the analysis purpose. The filter conditioning is important in order to achieve reproducible results.
