PYGC-450 Thermal Cracking and Release Instrument
In current scientific research, using a single instrument and equipment is no longer sufficient for studying the physical and chemical properties of substances. When necessary, it is necessary to combine two or more instruments, and this technology that combines two or more methods is calledJoint technologyRapid pyrolysis is a thermochemical technique that typically decomposes non gasified substances such as polymers into small molecules within seconds at 500 ℃. Pyrolysis gas chromatography-mass spectrometry (Py GC-MS) technologypyrolysisCombining technology with gas chromatography-mass spectrometryIt is suitable for analyzing refractory, insoluble, and complex organic mixtures without the need for sample pretreatment. It has the advantages of small injection volume and fast analysis speed, and is widely used in organic material detection. Solved the disadvantage of simple gas chromatography-mass spectrometry being unsuitable for difficult to melt, insoluble, and complex organic mixtures. The basic principle is an analysis method that combines thermal cracking technology and gas chromatography-mass spectrometry technology. It extends the application of gas chromatography-mass spectrometry to non-volatile organic solid materials. Trace amounts of polymer samples are rapidly heated in an inert atmosphere to generate cracking products. The cracking products are directly introduced into the gas chromatography system for separation, and then enter the mass spectrometer for detection. The characteristic fragment ions after high-temperature cracking are qualitatively analyzedquantitative analysisTo infer the composition and structure of the original sample.
