Residual-gas analysis (RGA), a mass-spectrometric method, is the most accurate method for measuring moisture and other low-molecular-weight volatile compounds released from polymeric materials. Interpretation of RGA data has at times proven difficult since small differences in the processing of samples intended to be identical resulted in major differences in the results and analyses of the same circuits by different laboratories. Most of these differences have been resolved by using laboratories that are certified by government agencies, such as Defense Supply Center at Columbus (DSCC), using their own standards.
