one single comprehensive two-dimensional gas chromatography with time-of-flight massspectrometry in electron ionization mode run, new synthetic routes were developed for five carbon-13-labeled γ-lactones and four deuterium-labeled δ-lactones, with the isotope label in the ring to be used in stable isotopedilutionassays. The concentrations of the nine lactones were then analyzed in raw and pasteurized
