OilPrints is a powerful program designed to display data generated by gas chromatography and gas chromatography-mass spectrometry (biomarker) analysis without the need for purchasing high-priced, machine-specific software. Automating correlations between samples for greater speed and convenience, this user-friendly program is designed to easily overlay, combine, zoom, and scroll multiple GC chromatographs or GC-MS fragmentograms at one time. It also allows the viewing, labeling, coloring, and printing of chromatographs or fragmentograms with user-defined parameters, including the ability to process the sample’s baseline, labels, and peaks with manual interface options that can be activated with ease and without the customary double, triple, and quadruple checks necessary in auto-saving programs.
