Many traditional methods for detecting airborne sources of contamination rely on the deposition of the contamination onto a surface. For example, surface swabs might be taken, or bioaerosol sampling might be undertaken with a sampler that relies on the impact of biological particles onto a solid growth medium. These methods are unable to deliver an accurate measurement of airborne load. In contrast, the Coriolis µ employs a wet-walled cyclone technology that improves bioaerosol sampling for bacteria, pollen, endotoxins, viruses and fungal spores.
By passing sample air through liquid in a cyclone, the Coriolis µ is able to collect airborne particles in a liquid at a high flow rate (300 l/m) with validated efficiency. The liquid containing the particles can then be analysed using one of a number of the latest rapid microbiological analysis methods.
