Latest Patents
Xiaona Shang's latest patents include a semi-online analytical apparatus for measuring atmospheric trace nitrogen-containing organic components. This advanced apparatus features a collision-type PM filter, 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 innovative apparatus can replace traditional filter sampling for collecting particulate matter, significantly freeing up manpower, saving resources, and reducing organic 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 PM can be increased by at least 10 times, enhancing the sampling capability of the apparatus. This technology achieves full automation of PM sampling and collection, making it widely applicable in air quality monitoring and health risk assessment.
Another notable invention is a kind of online PM concentrated collection instrument. This instrument includes five parts: a PM cutting head, a water tank system, a virtual cropping system, a condenser circulation system, and an online concentrated collection system. The water tank system contains a water tank, an electrical heating rod, and a temperature-controlled digital display device. The virtual cropping system consists of a virtual cutter, a concentrated air vacuum pump, and a main air vacuum pump. The condenser circulation system circulates condensate to grow the saturated particles, while the online concentrated collection system includes a biological sampling bottle, a solenoid valve with a relay, an automatic distillate collector, and a computer subdivision constant-current pump. This instrument can concentrate real PM samples by 7-10 times with high efficiency, providing technical support for subsequent online chemical component or toxicity tests.
