| titleOfInvention | A microplastic detection device and method based on pyrolysis-mass spectrometry technology |
| abstract | The invention relates to a microplastic detection device and method based on pyrolysis-mass spectrometry technology, which solves the problems of the complex structure, inconvenient operation, inability to accurately realize quantitative analysis of each component in microplastics, and ease of use in the prior art for microplastic content research devices. Affected by environmental interference, large errors, low accuracy, time-consuming and labor-intensive, the instrument occupies a large area, can only be operated in the laboratory, and is difficult to apply to the technical problems of on-site detection. The microplastic detection device based on pyrolysis-mass spectrometry technology provided by the present invention, the device as a whole is a closed gas circuit device system connected by pipelines, and the device is connected in sequence including a working gas source, a pyrolysis device, a filter and a mass spectrometer, After the microplastic sample is put into the pyrolysis device, the microplastic sample is pyrolyzed by the pyrolysis device, and the pyrolysis product of the microplastic sample, driven by the working carrier gas, is filtered by a filter and then enters the mass spectrometer for detection and analysis; At the same time, its method is provided. The invention is widely used in the technical field of microplastic detection. |
