|Description:||The field of Metabolomics is a hypotheses driven scientific “omics” field, that utilizes multivariate statistical analysis software tools to determine how statistically significant endogenous metabolites (or Lipids in the area of Lipidomics), change as a function of phenotype, disease state and/or condition. A typical metabolomics workflow includes many steps starting from Sample Collection/Storage, Sample preparation (protein precipitation/metabolite extraction), separation and detection using both gas phase (GC/MS) and liquid phase chromatography (LC/MS), data mining (unsupervised/supervised), statistical analysis of samples, identification of compounds, and determining if the observed changes match the proposed hypothesis when possible linked to a change in a biochemical pathway. The diverse nature of biological samples (biodiversity/population) adds an additional challenge to these experimental studies, in that the concentration of metabolites can vary greatly from biological sample to sample.|

|Details on the topic or technology covered:||
Design of Experiment (DOE) methods described in this presentation are utilized to measure and reduce system/measurement variability and help determine the number of samples required for a particular study. The presentation will discuss how one can reduce system variability and provide confidence in the measurements and hypotheses.
