Xenstats specializes in chromatographic data analysis for data obtained by the LC-MS, GC-MS, LC-UV, LC-FLR, Raman spectroscopy and Fourier transform infrared spectroscopy. We provide comprehensive analysis from raw data, through preprocessing and peak annotation to statistical analysis. For large chromatographic data sets, we additionally offer correlation network analysis. We use our own scripts in the R system and non-commercial programs.
