| Definition | The Thermo Scientific high temperature conversion elemental analyzer (TC/EA) is an isotope ratio mass spectrometer designed to measure simultaneous hydrogen and oxygen isotope ratios of all organic compounds and selected inorganic compounds. The Thermo Scientific TC/EA can be connected to any current Thermo Scientific isotope ratio mass spectrometer equipped for continuous flow applications. The instrument uses a quantitative, high temperature conversion technique referred to as pyrolysis, in which oxygen present in a compound is converted to CO, and hydrogen contained in a compound is converted to H2. The process is rapid and quantitative in a reducing environment at high temperatures, typically exceeding 1400 degrees celsius. The TC/EA is able to measure both H and O isotope ratios in a single run, which takes about 6 minutes. It takes about 5 minutes per sample for oxygen and less than 3 minutes for hydrogen isotope ratio determination. Optional modules can be added to the TC/EA which include a Liquid Injection Kit and a Bottom Feed Connector. | |
