Overview Purpose: UltraFast gas chromatography is applied to the analysis of essential oils. By means of direct resistively heated columns, the UltraFast Finnigan™ TRACE™ GC Ultra system achieves very fast temperature programming allowing the operator to significantly shorten the GC analysis time. Methods: Essential Oils are diluted 1 to 200 in cyclohexane and 1 μL of the resulting solution is then injected in split mode in the Ultra Fast GC. Results: The analyses are achieved with approximately a 30-fold speed increase with respect to the conventional GC methods with good accuracy and precision. The separation of critical pairs is optimized by choosing the properly selective stationary phase.
