Researchers at Purdue University have developed a method to identify predictive failure of electronic systems using chemical detection processes. Current methods to analyze failure of electronic equipment are largely reactive and can detect the failure after the damage has occurred. The Purdue researchers' method relies on the fact that microelectronics within a computing system have a unique chemical composition, and thus unique bulk chemical signature produced upon failure. By using mass spectrometry methods to analyze the signature release of an analyte before and after power failure, the method provides fault detection and diagnosis. This method is passive and does not interfere with system functionality. Using this technology, time and cost associated with power, space, and weight applications can be reduced for a variety of electronic equipment.

Technology Validation: The chemical detection method utilized Atmospheric
