COMSPARI (COMparison of SPectral And Retention Information) is a software that has been written to facilitate the analysis of “paired” samples, i.e. samples that are almost identical yet present some qualitative difference. The software was originally written for the analysis of data files produced by GC/MS and LC/MS, but can be used for other techniques, too.
