          Conclusions


          • The use of the CLAM-2000 as a fully automatic pre-treatment system for LC/MS-based metabolomics facilitates the
           identi cation of metabolite biomarker candidates, the validation of metabolite biomarker candidates, and the practical
           use of metabolite biomarkers.
          • Further optimization of our method for CLAM-2000-based metabolome analysis is necessary.
