We conduct untargeted metabolomics studies and targeted quantification of metabolites to investigate metabolic processes.





We pool our bio-analytical, statistical, medical, biological and biochemical expertise and combine it with advanced information technology. This strategy allows us to offer a wide range of customer-oriented services in the field of metabolomics and metabolic research.

Untargeted metabolomics and targeted quantification of metabolites


We provide a wide range of metabolomics services on targeted and untargeted analytical platforms. Our expertise comprises the correct choice of sample types, sample collection procedures, sample storage and delivery, sample preparation in combination with the best metabolomics platforms. Furthermore, data processing and statistical analysis methods are well established .

  • Metabolites of primary metabolism (amino acids, Krebs cycle, glycolysis, pentosephosphate pathway, CoAs, …)
  • Energy metabolism
  • Metabolite fingerprinting
  • Quantification of coenzyme-A activated compounds
  • Quantification of spermidine and relatives (polyamines)
  • Stable isotope labelling (SIL) supported metabolomics

Our Expertise


We provide flexible, solutions tailored to your needs and cover the complete study or only single steps ranging from support in study design, data generation (extraction, targeted/untargeted measurement) to analysis (feature detection, normalization, quality control, corrections, identification), interpretation (visualization, uni-/multi/-variate statistics) to knowledge generation (experienced scientists).

  • Sample preparation        
  • Data processing: visualization, filtering and correction
  • Metabolite identification
  • Univariate and multivariate statistical methods
  • Sample types: muman, mouse, rat, pig, drosophila and a wide variety of microbial species and cell cultures
