The PS 30 particle sampler detect the overall spore total (cultivable and non-cultivable ) in the air.

During particle sampling, airborne particles are made to impact fluidically via a slot jet onto a transparent object slide coated with adhesive.

The particles are deposited onto a compact collection gauge 1.1 mm wide and 16 mm long.

The slide loaded as described can subsequently be stained directly after the sampling (without cultivation) and evaluated using a light optical microscope. Unlike airborne spore sampling, in this case, the germination capacity of the particles is not relevant to the result, since each spore is detectable and countable in the microscope. Thanks to the high filtration efficiency of the particle collector, even agglomerates and aggregates of bacteria can be detected and counted.

In addition particle sampling also reveals very fast information over non-microbiological disturbances in the air such as fibres, inorganic particles (e.g. abrasive particles from production facilities).

The PS 30 particle sampler head is operated with our convenient MBASS30 system or with a separate pump

The performance specifications of the PS 30 particle collector:

• Detection even of non-germinable spores and particles
• Collection of spores, pollen, fibres, dandruffs and other micro particles in air and gas on adhesive coated standard slides
• Up to 3 samplings on a single slide through adjustable slot nozzles
• Sampling from all operating positions by slide fixing
• Sampling of hollow spaces via hose connection to the sample air intake
• Uniform operating volume flow of 30 l/min as with the LKS 30 air sampler and FA 30 filter adapter
• No cultivation time - evaluation possible immediately after sampling
• No temperature and time restrictions for sample transport
• The methods conform to the VDI (German Association of Engineers) Guideline 4300 part 10

Its many advantages mean the PS 30 particle sampler is today the standard product of choice for expert surveys and in building biology. During the round robin tests conducted for "Sampling of mould spores in the air - particle collection" by the Berufsverband der Deutschen Baubiologen VDB e.V. (Professional Association of German Building Biologists)(www.baubiologie.net)  in 2010. All participants used the PS 30 particle sampler.
