Application of gas chromatography in analysis of a cold plasma jet generated by an atmospheric pressure microwave discharge in argon flow was considered. Previously developed 2.45-GHz-plasmatron with the external 6-rod-electrode plasma torch was used as a microwave plasma source. The analysis of gaseous samples showed that CO concentration increases by 5-6 times and new gaseous products appear – H 2 and CH 4 as a result of plasma-gas interaction. The production of CO, H 2 and O 2 occurs in the processes of dissociation of CO 2 and water vapor in the nonequilibrium plasma through the vibrationally excited states.
