Determining and identifying individual analytes within a complex sample can provide important information to better understand a product or process. This exploratory analysis is readily accomplished with GC-TOFMS, as it provides non-targeted data with every acquisition. The Pegasus BT adds to the chromatographic separation by taking advantage of the full mass range data with mathematical deconvolution to further separate chromatographic coelutions. These capabilities provide excellent information about a sample and the ChromaTOF brand software contains tools to help streamline data analysis.
