A continuous-flow pyrolysis interface for gas chromatography/isotope ratio mass spectrometry (GC/IRMS) has been developed for 2 H analysis of individual organic compounds. Pyrolysis of gas chromatographically separated fatty acid methyl esters is performed at 1200 Β°C in an unpacked alumina tube to c

## Abstract __N__βacetylaspartic acid (NAA) is a specific urinary marker for Canavan disease, an autosomal recessive leukodystrophy. We developed a βdilute and shootβ stable isotope dilution liquid chromatography tandem mass spectrometry (LCβMS/MS) method for determination of NAA in urine. Deuterat
