摘要: In this study, usual methods commonly applied to report the quantitative composition of flavours, fragrances and essential oils were compared. The MS determinations without response factors exhibited a lack accuracy reproducibility. FID provided better results, but still unsatisfactory. best results obtained by true internal standardization in FID, which is time-consuming for mixtures composed many constituents. use factor database was thus proposed validated testing dependence on GC parameters, using an experimental design. Very low time variations observed. Under standard conditions, determination model mixture with four different instruments mean bias < 3.4%.
