[0035]Example 1:
[0036]The atmospheric particles were screened by the cyclone PM2.5 cutting head 7, and the particle diameter of less than 2.5 microns entered the dissolution 7 removal of acid and alkali gas, and the passed particles entered the water tank 9 of the constant temperature 45 ± 2 degrees Celsius 9 wrap the water vapor and reached a supersaturation state. , Saturated ions under a condensation pipe 14 of the main air flow vacuum pump under the high flow mass flow controller 5, upstream to the condensation pipe 14 set to be provided to thermostat -19 ± 1 degrees Celsius, up to 3-4 The droplets of microns are passed through the nozzle 19 in the virtual cutter 17, and the droplets obtain accelerate into the concentrated gas path, and the gas enters the bypass gas outlet, so that the particulate concentration is 10 times. Concentrated droplets were extracted from the biological sampling bottle 21 by setting a float flow meter 1 control 5 ± 0.2 liters per minute, sprayed into t...
