摘要
The present invention relates to a microplastic detection device and method based on a pyrolysis-mass spectrometry technology. The microplastic detection device based on a pyrolysis-mass spectrometry technology provided by the present invention is substantially a sealed gas path device system formed connected via pipelines. The device includes a working gas source, a pyrolysis device, a filter and a mass spectrometer which are connected in sequence. After a microplastic sample is placed into the pyrolysis device, the microplastic sample is decomposed in the pyrolysis device, and pyrolysis products from the microplastic sample driven by a carrier gas of the working gas source enter the mass spectrometer for detection and analysis after being filtered by the filter. Furthermore, the present invention provides a microplastic detection method based on a pyrolysis-mass spectrometry. The present invention is widely applied to the field of a microplastic detection technology.
