FIELD: chemistry.
SUBSTANCE: method involves feeding a sample for analysis; converting methane to an analyte in air or oxygen-containing gas; feeding the analyte for analysis; ionising the analyte; isotopic analysis of ions of the analyte using a mass-analyser. The analyte is methanol and conversion is carried out via gaseous electrical discharge.
EFFECT: invention reduces requirements for a vacuum system and operating conditions of an isotope mass spectrometre, degree of purification of gases; there is no need for cryogenic beneficiation of methane or the analyte.
