Instrument and method for sealed penetration of rigid packaging to measure internal oxygen concentration with an optical oxygen analyzer

摘要

An assembly and method of using the assembly. The assembly is operable when assembled as a benchtop instrument for sealed penetration of an oxygen sensitive luminescent sensor into sensible communication with an enclosed space of a sealed rigid package to measure oxygen concentration therein, and operable when disassembled as a handheld instrument for sealed penetration of the oxygen sensitive luminescent sensor into sensible communication with an enclosed space of a flexible package to measure oxygen concentration therein. The assembly includes a mechanical punch press equipped with a longitudinally reciprocable fixture equipped with a hollow piercing member, and an oxygen analyzer releasably attachable to the fixture.
