Quality control of essential oils, fragrances, and perfumes is typically performed by GC-FID analysis. Important GC performance criteria are resolution, stability of retention times and indices, and sample throughput. This Application Note describes the transfer of a reference method developed on an Agilent 7890 GC to the Agilent Intuvo 9000 GC, with the comparison of data obtained on typical fragrance and essential oil samples. It demonstrates that data quality is maintained on the Intuvo 9000 GC, while sample throughput can be increased using shorter narrow bore columns.
