Abstract

The invention discloses a multi-stage biological aerosol sampler, which includes several cyclone samplers and sampling pumps connected in sequence, the cyclone sampler includes a collection chamber, the upper part of the collection chamber is provided with a liquid replenishment chamber, and the collection chamber A liquid replenishment tank is provided, the bottom of the collection chamber communicates with the sampling liquid collection bottle through a liquid collection pipe, an exhaust and liquid replenishment hole is arranged in the liquid replenishment chamber, an air intake pipe and an exhaust pipe running through the liquid replenishment chamber are arranged in the collection chamber , the sampling pump communicates with the exhaust pipe of the last stage cyclone sampler. The invention has simple structure, can reduce the damage of microorganisms in the sampling process, and can perform multi-stage sampling.

Description

technical field [0001] The invention relates to an air sampler and a method, in particular to a multi-stage biological aerosol sampler and a sampling method. Background technique [0002] According to the statistics of the World Health Organization, respiratory exposure to bioaerosols may lead to various respiratory diseases including SARS, H1N1, asthma, allergies, etc., and nearly 3 million people die each year. Applied basic research integrating bioaerosol capture, monitoring, and inactivation protection has great demand in the fields of atmospheric environment, food safety, public health, and environment and health, and the collection of bioaerosols is a crucial first step. [0003] According to the microbial collection surface, it can be divided into samplers that capture air microorganisms on solid medium or other adhesive surfaces, samplers collected in nutrient solution, and samplers collected on filter membranes or other filter materials; The collection methods can ...
