ABSTRACT
Two methylation methods are compared in relation to the determination of low levels (less than microgram/ml) of the acidic metabolite of bezitramide in human urine. It was necessary to use alkali flame ionisation detector, which specifically detects nitrogen-containing compounds. Several difficulties associated with the use of this detector are described.
