Abstract
The disclosed apparatus includes a collision-type PMfilter, a resistive heating rod with a temperature sensor, a sealed water tank, a condensation system, a virtual concentrator, a flow controller, a vacuum pump, a particulate matter collection bottle, dimethylacetamide reagent, an ultrasonic bath, a fraction automatic supply/collect integrated pump, a vacuum parallel concentrator, a micro-injection pump, and a liquid chromatography-time-of-flight mass spectrometer. This apparatus can replace traditional filter sampling for collecting PMgreatly freeing up manpower, saving resources, and reducing organics loss in PM. The collected sample solution is injected into the liquid chromatography-mass spectrometer for online analysis of organic components. By introducing an enrichment system, the concentration of sample PMcan be increased at least by 10 times, enhancing the sampling capability of the apparatus. This apparatus achieves full automation of PMsampling and collection. This apparatus can be widely applied in air quality monitoring and health risk assessment.
