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.
