Abstract : This report covers Task 2: Algorithm Development and Performance Analysis, for the program Development of a Handheld Chemical Detector Using Microchip GC. The study described in this report addresses the algorithmic performance requirements for the concept handheld instrument for vapor detection of CW-related materials using microchip GC. Included in this report are example signal processing and algorithmic analyses using actual microchip GC data. An overall algorithmic approach for the concept handheld CW detection instrument is developed and presented. Approaches investigated in this study include: pre- processing of chromatograms by different smoothing methods; the application of various peak detection methods; chromatographic correlations using CW data reference tables; and algorithms for merged peak analysis. To best illustrate the robustness of the recommended approach, our signal processing approach is successfully applied to several microchip GC data sets which confound existing methods. CW Agent Detection, Microchip Gas Chromatograph, Correlated Gas Chromatography, CW Treaty Verification.
