Résumé
After sampling and preparation of the laboratory sample the gaseous test portion is passed at a given rate through an electrochemical cell previously calibrated with air or with standard mixtures containing a known amount of oxygen, and the concentration of oxygen in the gaseous olefin is measured. The method is applicable to light olefins having an oxygen content greater than 1 milliliter per cubicmeter.
