Abstract

A non-destructive resonance (NDR) method of measuring and controlling an O 2 fraction, a CO fraction, or a CO 2 fraction in a gas process stream. The method includes: determining the resonance frequency of an off-line standard gas composition; scanning a predetermined characteristic parameter around the predetermined resonance frequency; plotting a first 3D chart to obtain a 3D vector; flowing gas through the NDR system; on-line scanning a corresponding on-line measured parameter around the resonance frequency, and recording the same; plotting a second 3D chart to obtain a 3D vector which precisely identifies the value of the second measured parameter; comparing a 3D standard first vector to the 3D measured second vector; and correlating between a relative characteristic parameter change and the change in the gas fraction.
