PPT-1. Why we need quantitation?

For translating MSbased metabolomics to biology we need to know quantityconcentrations of identified molecules Q tion can be used to model metabolomic networks and to see fluxes Ionization is a complex process and no all compounds are forming ions is the same way NMR signal intensities are much less sensitive to the chemical structures differences. It permits accurate quantitation versus aqueous standards even when the sample matrix causes changes in the timing or shape of the analyte peak absorption signal For example Figure 1 shows the signals obtained with similar concentrations of lead in Lab 8.
