Equipment 7 piece(s)
Consists of high temperature oxidation and reduction furnaces inline with a water trap and a gas chromatograph for analyzing solid materials for isotope ratio and elemental determinations. Interfaced with the DeltaVPlus IRMS for analysis of N2 (δ15N, %N) and/or CO2 (δ13C, %C).
Preparation system utilizing acid injection to digest carbonates for isotope ratio analysis. Interfaced with the DeltaVPlus IRMS for analyzing headspace from vials for carbon and oxygen isotopes (CO2: δ13C, δ18O).
Analyzes water samples for inorganic and/or organic carbon content by using a wet chemical oxidation process to extract carbon as CO2 gas, which enters a NDIR detector for ppmC determination. Interfaced with the DeltaVPlus IRMS for simultaneous carbon isotope ratio analysis (δ13C-TOC and δ13C-TIC).
