Furthermore, because NMR permits the measurement of concentrations spanning up to five orders of magnitude, several problems can arise with data analysis. If the NMR spectra are mis-phased or if the baseline correction is flawed, the estimated concentrations of many compounds will be systematically biased.
For instance, if the NMR spectra are incorrectly referenced or inconsistently aligned, the identification of many compounds will be incorrect.
However, the quality and utility of these insights can be profoundly affected by how the NMR spectra are processed and interpreted. 1H NMR spectra from urine can yield information-rich data sets that offer important insights into many biological and biochemical phenomena.
