ABSTRACT:
A method to efficiently measure the oxygen content of both the headspace and fluid within a hermetically sealed container. A container is pierced using a hollow needle with the interior space sealed from the outside and the tip of said hollow needle removed, and the interior space is made continuous with the headspace within the container. A probe of a fluorescent oxygen concentration meter is inserted through the hollow needle to the interior of the container, positioned in the headspace within the container, and the oxygen concentration of the headspace3is measured. The probe is inserted further so that the fluorescent material is submerged in the fluid inside the container, and the dissolved oxygen concentration inside the fluid is measured.
