Analysis of Essential Oils by Fast Capillary GC Using the Agilent 6890 Series GC

Abstract: By reducing the internal diameter of the capillary column, a higher efficiency per unit of column length is obtained in capillary GC (CGC). The application of narrow bore columns, therefore, results in faster analyses compared to conventional columns while maintining the resolution. The use of narrow bore columns in routine analysis, however, makes high demands on instrumentation. The 6890 Series GC offeres electronic control of column flow and split flow, faster oven heating and faster electronics, making fast capillary GC accessible for routine applications. Method translation software is an additional tool to translate an existing operating procedure into a method using narrow bore column. The performance of the 6890 Series GC in fast CGC is demonstrated by the analysis of some essential oils.
