The TOC-Analyzer isotope interface was developed at the University of Ottawa, Earth Sciences Department in the G.G. Hatch Isotopes Laboratories. The device conditions the output from a TOC-Analyzer by scrubbing and separating the effluent gases of reaction. After conditioning, the effluent gases are swept into a Thermo Delta or MAT 253 stable isotope mass spectrometer for analysis, via the ConFlo IV.
