Automated interpretation of infrared spectra with an instrument based minicomputer

Abstract: 2367higher detection limit, is probably due to surfactants still present in solution after cleanup. If lower limits are desired for a particular application the extended cleanup procedure can be used with the TEA via direct injection. The additional steps do not provide sufficient cleanup to increase detection limits via the D P P method.Thus an analyst has available a choice of methods depending on levels. In either case preparation times are short;for whole blood an average time is approximately 10 min. Chal… Show more

“…IntIRpret has five main subroutines: the interferogram processing and peak selection subroutine (PUSHSUB) (8), the automated knowledge acquisition subroutine (AUTOGEN) {16), the system optimization subroutine (STO), the inference engine (PAIRS) (7,(10)(11)(12)(13)(14)(15)(16), and the final processing subroutine that subtracts spectral similarity (PAIRSPLUS) (8). Figure 1 is a flow chart of the intIRpret process, where the logic of each of the five major subroutines is diagramed.…”

“…Two limitations of PAWMI were that once a training set, consisting of a library of reference of spectra, was defined, the rules for the inference engine (PAIRS) (10)(11)(12)(13)(14)(15)(16) had to be generated manually. The second limitation was that the PAWMI compound identification software only uses peak location information.…”

“…A number of programs have been developed to assist the chemist in the identification and quantitation of unknown compounds. Many approaches to automated spectral interpretation have been developed such as pattern recognition, factor analysis, hierarchical clustering, and expert systems (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). Summaries of recent literature in this and related subjects are available in symposium proceedings (19,20).…”
