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.

摘要： An ionization detector that reduces the filtering effects of the ignition coil inductances by shorting an inductance of a primary winding of the ignition coil. The ionization detector includes a bias voltage source and an inductance control switch. The bias voltage source supplies electric voltage across an electric gap of a spark plug for detecting ionization within the combustion chamber. The inductance control switch is electrically parallel with a primary winding of an ignition coil and is operable to short an inductance of the primary winding.

摘要： In a gas analysis apparatus including analyzers that need ignition, such as FIDs, in order to make it possible to surely ignite the analyzers while downsizing the entire apparatus, the apparatus includes first and second analyzers to accept a sample gas, a first gas line provided with the first analyzer, a second gas line provided with the second analyzer and joined downstream of the first analyzer in the first gas line. At least one of the first analyzer and the second analyzer is configured to cause pressure fluctuations in the gas line including the analyzer when analyzing the sample gas. A first backflow prevention mechanism is disposed between another of the analyzers and a junction of the gas lines. The first backflow prevention mechanism is configured to prevent a fluid from flowing backward from the one of the analyzers through the junction toward the another of the analyzers.

摘要： The present invention is directed to a method and device to desorb an analyte using heat to allow desorption of the analyte molecules, where the desorbed analyte molecules are ionized with ambient temperature ionizing species. In various embodiments of the invention a current is passed through a mesh upon which the analyte molecules are present. The current heats the mesh and results in desorption of the analyte molecules which then interact with gas phase metastable neutral molecules or atoms to form analyte ions characteristic of the analyte molecules.
