Quick-change inlet port adapters allow the CEGS to easily accept organic, carbonate, and gas samples. Stepped-temperature combustion is built-in. Any fraction can be analyzed or discarded independently of the others.
A column of hot quartz media, loaded directly into the combustion tube, ensures that all carbon is fully oxidized. It also mitigates the intrusion of contaminant particles into the vacuum system. A 20-micron frit provides further protection. Additionally, the fan-cooled stainless steel trap immediately above the combustion chamber catches room-temperature-condensable combustion gas products. Together, these measures work to keep the inlet port and the rest of the vacuum system clean for years of service.
