ELEM-SPOT™
Element Selective Gas Chromatograph Mass Spectrometer
Limit sales to areas where utilities can be procured and systems can be supported.
Biomass energy, chemical recycling, and other new technologies are being researched and developed around the world in an effort to achieve a carbon-neutral society. However, there is concern that, unlike conventional fossil fuels, new raw materials generated from such R&D efforts may contain hydrocarbon mixtures that could have a detrimental effect on product quality or production processes. Of the hydrocarbons involved, it can be particularly difficult to detect heterocyclic compounds selectively with high sensitivity. Shimadzu’s unique ELEM-SPOT system is the world’s first Gas Chromatograph Mass Spectrometer (GC-MS) with an element-selective combustion unit (EL-30) included for selectively analyzing nitrogen-containing compounds or oxygenated compounds in complex hydrocarbon compounds with high sensitivity.
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.
