The ChromIdent Pyro Bundle is used to create, query and extend databases from GC/MS data. The database query is based on a peak list comparison. This allows components of e.g. pyrolyzed complex samples to be determined and the total sample to be identified. The bundle includes the chromatography evaluation software OpenChrom GERSTEL Enterprise Edition with the additional plugin ChromIdent for database evaluation as well as the GERSTEL Pyro Database.
