Abstract
The oxidation and reduction of organic compounds in the gaseous, liquid, and solid states were studied using a Delta Plus XP isotope mass spectrometer. The oxidation and reduction were performed for substances with simple and complex molecular structures: methane (natural gas standard RM 8561 HGS3), ethanol, pyridine, benzyl alcohol, n-undecane, and cysteine; the reduction was performed for water and methanol. Based on these data, it was concluded that the complex organic compounds were almost completely oxidized, while water and oxygen-containing organic substances were completely reduced in the developed electrochemical solid-electrolyte reactor (SER). The use of this reactor in the optimum mode did not change the isotope composition of carbon and hydrogen in the analytes. SER can successfully replace the oxidation and reduction reactors used in isotope-ratio mass spectrometry.
