    摘要： An instrument (10) for detecting leaks in a hermetically sealed package (100). The instrument (10) includes a hollow needle (20), a mass flow rate sensor (50) in sealed fluid communication with a lumen (29) defined by the hollow needle (20), and a vacuum pump (40). The vacuum pump (40) is in fluid communication with the lumen (29) defined by the needle (20) for evacuating gas from the hermetically sealed package (100), and in fluid communication with the mass flow sensor (50) for detecting mass flow from the evacuated package (100) into operable contact with the mass flow rate sensor (50) so as to permit sensing of any continuing mass flow from the evacuated package.

    摘要： An instrument (10) for detecting leaks in a hermetically sealed package (100). The instrument (10) includes (i) a hollow needle (20), (ii) a mass flow rate sensor (70) in sealed fluid communication with the lumen defined by the hollow needle (20), and (iii) a vacuum pump (60). The vacuum pump (60) is in fluid communication with the lumen defined by the needle (20) for evacuating gas (102) from the hermetically sealed package (100), and in fluid communication with the mass flow rate sensor (70) for directing mass flow from the evacuated package (100) into operable contact with the mass flow rate sensor (70) so as to permit sensing of any continuing mass flow from the evacuated package (100). The instrument (10) may further include an oxygen sensor (40) in sealed fluid communication with the lumen defined by the hollow needle (20) for analyzing the oxygen concentration of the gas (102) within the hermetically sealed package (100).

    摘要： A needle valve (10) with a hollow needle (70) effective for permitting a portion of the fluid passing through the valve to flow throughout the valve and exit through any leaks in the valve, whereby any environmental fluid within the valve is displaced by the fluid passing through the valve.

    摘要： A sensor for detecting volatile organic compounds in ambient air by positioning a detection cell adjacent a gas discharge device to cause molecules of organic compounds to become ionized, and applying an electric field across the collection cell to attract ions and free electrons formed in the cell to develop a current, and amplifying the current magnitude so created.

    摘要： A humidity control system for an analyte permeation testing instrument. The system includes (i) an analyte permeation testing instrument, (ii) a sensor for sensing a target analyte, (iii) a humidity control chamber, and (iv) a selectively permeable membrane permeable to water vapor and impermeable to the target analyte. The analyte permeation testing instrument defines a testing chamber operable for engaging a test film such that the testing chamber is sealingly separated by the test film into a first cell and a second cell throughout a permeation testing period. The sensor is placed in fluid communication with the first cell. The humidity control chamber is positioned adjacent the first cell and in fluid communication with both a source of gas having a known humidity and the first cell, with the selectively permeable membrane sealingly separating the humidity control chamber from the first cell.
