Thermo Finnigan GC Combustion/Interface III

The Finnigan GC-C/TC III interface from Thermo Electron Corporation is a state of the art GC interface for the analysis of ¹³C/¹²C, ¹⁵N/¹⁴N, ¹⁸O/¹⁶O, and D/H. Organic compounds eluting from a GC column are converted into simple gases when traversing a capillary micro-reactor. Accordingly all compound specific isotope ratios can be analyzed in the IRMS.

The Finnigan GC-Combustion/Interface III is equipped with a Backflush system for eliminating all solvents in front of the oxidation furnace. The Backflush reverses the flow through the oxidation reactor towards an exit directly after the GC column to cut off all eluting solvent. All valves are kept outside of the analytical flow path to ensure the cleanest combustion conditions and leaving all GC related parts untouched, thus retaining the highest GC performance.
