Modelling the acid/base (1)H NMR chemical shift limits of metabolites in human urine
INTRODUCTION: Despite the use of buffering agents the (1)H NMR spectra of biofluid samples in metabolic profiling investigations typically suffer from extensive peak frequency shifting between spectra. These chemical shift changes are mainly due to differences in pH and divalent metal ion concentrat...
