Measurements were carried out with a Johnas, an Andersen cascade impactor and a PM10 separator monted on a Tecora. The results were compared with each other and with the results of dust concentrations measured with a Tecora in accordance with ISO 9096. ...
These processes depend on the inertial properties of the particles, such as size, density and velocity, and on the physical parameters of the impactor, such as inlet-nozzle dimensions, jet-to-plate distances and airflow velocities and paths. Because of differences in physical characteristics, samplers differ in collection efficiency, often referred to as “cut-off” size (d50) ...
You can sample for culturable fungi using an Andersen impactor, SAS sampler, RCS Biotest sampler, or an all-glass impinger. The Andersen impactor and SAS sampler are similar devices in that both use agar plates. Air is vacuumed through a sieve-like cover thereby forcing particles to adhere to the agar´´s surface. The ...
