title: A new technique for the detection of metabolites labelled by the isotope 13C using mass fragmentography.
abstract: The detection of a small amount of 13C labelled methyl benzoate and its metabolites in human urine dosed 13C labelled aspirin was carried out by a new mass fragmentographic technique.
