ChromaTOF® is a robust software suite that eases the understanding and processing of gas chromatography and mass spectrometry data. ChromaTOF works automatically with the Pegasus GC-TOFMS instruments, turning your data into usable information. ChromaTOF Tile speeds up data analysis by isolating peaks of interest with Fisher-based tile ratios. The Idenfication Grading System (IGS) allows users to compare data against known analytes to help quickly identify compounds in their samples.
