摘要： An oxygen-sensitive probe having reduced cross-sensitivity to humidity and methods of manufacturing and using such probes to measure oxygen concentrations within an enclosed space. The probe includes a thin film of an oxygen-sensitive photoluminescent dye on a first major surface of a microporous wettable polyolefin support layer. The dye is preferably a solid state composition comprising the oxygen-sensitive photoluminescent dye embedded within an oxygen-permeable hydrophobic polymer matrix.

摘要： A method for measuring the transmission rate of an analyte through a film. The method includes the steps of (i) separating a chamber into a first cell and a second cell with a known area of a film, (ii) flushing the first cell with an inert gas to remove any target analyte from the first cell, (iii) introducing a gas containing a known concentration of an analyte into the second cell, (iv) sealing the first cell to gas flow through the first cell, and (v) sensing any analyte in the first cell with a sensor that consumes the analyte at a rate greater than the rate at which the analyte is passing through the film, until a steady state rate of analyte consumption is measured by the sensor.

摘要： An instrument and method for measuring the volume of a hermetically sealed, variable volume, pressure conforming container. The instrument includes a needle, a vacuum pump, a mass flow rate sensor and an integrator. The needle has a lumen operable for sealingly perforating a container and thereby placing the lumen of the needle in fluid communication with a retention chamber defined by the container. The vacuum pump evacuates the gaseous content from the retention chamber through the lumen defined by the needle and past a mass flow rate sensor for sensing mass flow rates pulled through the lumen and transmitting corresponding mass flow rate signals over time to the integrator. The integrator is programmed to integrate the received mass flow rate signals over time through achievement of an evacuated retention chamber to generate a total mass value, and calculate a volume from the total mass value employing the Ideal Gas Law.
