eng	Analysis of Perfumes by Using Multi-Dimensional Gas Chromatography	This research deals with the analysis of volatile organic compounds in natural perfumes such as Praga Alchymica, which is produced by Rafaella. Rose Taif and Rose Josefina are additional samples. For analysis of volatile substances headspace and gas chromatography-mass spectrometry (GC/MS) have been used as these are frequently used methods for parfume analysis. The results indicate that nature of pure perfume like Rose Natura and Rose Taif has different compounds without 1-linalool as both of them have different smells. The same substances from Rose Taif and other aromas were measured in this parfume. Praga Alchymica was mixed from Rose nature and unknown flavor. This research also proved that for small amount of samples it is better to use GC/MS compared to headspace GC. Research will also entertain using “heart-cut” MDGC system with using chiral columns in the second dimension. In contrast with conventional GC/MS, heart-cut (H/C) MDGC instrumentation enables the transfer of selected bands of overlapping compounds from a primary (1D) to a secondary (2D) column, connected bymeansof an interface (either a switching valveor a Deans switch).
