✦ Synopsis
Orange essence oils of the Navel and Valencia variety were analyzed by GC and G U M S using two parallel capillarycolumns of different selectivity. Data were normalized, converted into a computer compatible format, and transferred via an asynchronous communications interface to a mainframe computer for statistical treatment, using the chemometrics software package ARTHUR. After suitable preprocessing of the raw data, reliable classificationwas possible. It appears that foursubstances which are present in both varieties can be used for that purpose.
