Biological aerosols 微生物採樣器

The study of the microbial content of the air has become increasingly more significant in the past decade as the need for “contamination free” environments have become more apparent.

Biological aerosols have been defined as viable biological contaminants occurring as solid or liquid particles in the air. These particles can vary in size from viruses less than 0.1 micron in diameter to fungal spores 100, or more microns in diameter. They may occur as single, unattached organisms or as aggregates. Viable particle samplers have been used to collect and study aerobic species of bacteria and fungi. Even though many viable samplers, including the Tisch Environmental sampler, will collect some virus particles, there is no convenient, practical method for the cultivation and enumeration of these particles. There are two constraints on all viable particle samplers, first, the particle must be separated from the air for any viability study, and second, the ability to reproduce (viability) must be demonstrated.

Personal Cascade Impactor

Our Personal Cascade Impactor is a precision cascade impactor worn by personnel to provide complete and accurate aerodynamic particle size distributions of the particulate in their environment. A personal mounting bracket is provided to attach to the subject’s lapel or pocket. It is compact, light-weight (7 oz. Max.) and are available with 8, 6, or 4 impactor stages all followed by a built-in filter holder. This product utilizes the radial slot design that is acclaimed for its accuracy and minimal internal losses and absence of particle bounce. Particle cut-points for this series of impactors range from 21 to 0.5 microns. Series 290 Marple Style Personal Cascade Impactors are operated at a flow rate of 2 LPM. Constant Flow Personal Sampling Pumps are attached to the belt and interconnected via tubing to the cascade impactor.
