  • Patent number: 9575006
    Abstract: A method, computing system and computer program product are provided to facilitate the inspection of an air separation module and to determine the degradation of an air separation module tubesheet. In the context of a method, an air separation module tubesheet is subjected to infrared spectroscopy by exposing the air separation module tubesheet to a spectrum of infrared radiation and collecting a spectrum of return signals. The method also includes providing a regression model based upon a multivariate regression of a representation of the infrared spectra collected from a plurality of air separation module tubesheet samples having different predefined conditions. The method further includes determining a condition of the air separation module tubesheet based upon a representation of the spectrum collected from the air separation module tubesheet and the regression model.

  • Patent number: 7872465
    Abstract: A method of evaluating material volatility characteristics. A pulse of current flux is delivered through a material sample to simulate a lightning strike. A pressure produced by the sample during the pulse is measured. The measured pressure is used to measure volatility of the material. An apparatus for evaluating the volatility of materials includes a pulse power supply and a test cell through which a pulse is delivered and in which pressure produced by a sample during the pulse is measured. This apparatus and method can reduce the costs of material selection and can shorten development time for new products.
