Oxygen Analysis OverviewAnalysis for oxygen is conducted using an oxygen analyzer. This instrument pyrolyzes a small portion of sample in an inert atmosphere (helium) to create the pyrolysis byproduct, carbon monoxide (CO). CO is then separated and quantified by a thermal conductivity detector.
Sample PreparationSamples are prepared by weighing a sample portion into a capsule (typically made of silver foil), carefully crimping the capsule and then loading it into an auto sampler. Typical masses taken for this test are between 1 and 4 mg. The autosampler drops the sample capsule into a closed chamber where the pyrolysis occurs.
Galbraith’s method for oxygen is based on industry accepted methodology. It also includes additional QC requirements to ensure the accuracy of results.
