ELEM-SPOT – GC-MS elemental analysis solution

Description

Principle of Detecting Oxygenated Compounds If now-common CxHyNzOw hydrocarbons are directly detected by FID or GC-MS after column separation, then they are detected based on a single peak. If that peak is detected by GC-MS after column separation and oxidative dissociation, and further analyzed by m/z, then MS chromatograms are obtained for each product of oxidative dissociation. Since the dissociation products are unique for each element contained in the compound, a unique chromatogram is obtained for each specific hetero-element contained in the compound. In the analysis of oxygenated compounds, oxidative decomposition is performed using isotopic oxygen (18O2) in the carrier gas, and screening is conducted to separate oxygen-containing compounds from other components. Dedicated data analysis tools are employed to accurately identify oxygen-containing compounds. 18O2 (Isotopic) Oxidation Gas 16O2 Oxidation Gas ELEM-SPOT, UFMS, LabSolutions and ClickTek are trademarks of Shimadzu Corporation or its affliated companies in Japan and/or other countries.
