Quantification, retention and system suitability kit consisting of two vials of metabolite mixes, which are dried down powders of metabolites that are either unlabeled or stabled isotope-labeled used to assess the performance of mass spectrometry based metabolomic workflows, both at the method level and at the analysis stage, and to help profile and quantify metabolites in experimental samples, for use in scientific research
