Abstract:Bioaerosol monitor is a kind of new instrument for fast and real time monitoring of air bioaerosol. The study evaluated the counting efficiency of the total particle channel and fluorescent particle channel of bioaerosol monitor instrument. First, a set of evaluation device for counting efficiency of bioaerosol monitor was designed and built. Then, the monodisperse and stable fluorescent polystyrene microspheres were prepared by SI-ATRP method. Bioaerosol environment was generated by atomizing fluorescent particles and found that the counting efficiency of total particle number and fluorescence particle number was 98.9% and 98.1%, respectively. The results showed that the device can meet the needs of the evaluation of the counting efficiency of the fluorescent bioaerosol monitor. It provided a scientific method for systematically evaluating the counting efficiency of a bioaerosol monitor, and the result was of great significance to the detection of bioaerosols.
