Cleanroom Technology (part of Dalhousie's HERC Lab)
This area is kept free of dust and debris. Filters are weighed in triplicate using a sensitive microbalance and anti-static blower. Relative Humidity is maintained between 30% and 40% and temperatures are kept between 20 and 25 degrees Celsius.
Effective Black Carbon (part of Dalhousie's HERC Lab)
Effective Black Carbon (EBC) is measured via reflectance, using a Diffusion Systems Smoke Stain Reflectometer (SSR). Total EBC is logarithmically dependent on reflectance R. We quantify absolute EBC using a conversion constant.
