Real-time online sampling and enrichment of PM2.5 in environment, simulating exposure of animals in high PM2.5 concentration weather.

Avoid PM2.5 particle contamination and particles physical damage caused by ultrasonic separation, membrane shedding and VOC loss existing in traditional membrane collection methods, retain harmful substances on PM2.5 particles and maintain particle size in the process.

Particle size concentration 0.1-2.5μm by 6-10 times, output flow rate up to 40-60 L/min.

Can be connected to rodent whole-body exposure system to perform PM2.5 high-concentration inhalation exposure tests.
