Ambient Sampling Mass Spectrometry and Chemometric Analysis for Screening Encapsulated Electronic and Electrical Components for Counterfeits

摘要

A method and apparatus for identification of a counterfeit electronic component, subjecting a suspected counterfeit electronic to an analytical method of ambient surface analysis to desorb and ionize compounds directly from a suspected counterfeit electronic surface with no pretreatment, detecting the resultant ions, comparing the identified ions to known standards, and returning a confidence that the suspected counterfeit electronic being analyzed is counterfeit.
