快速GC/TOF MS对精油的表征

Natural flavouring materials, such as essential oils are complexhydrophobic mixtures usually steam distilled or solvent extracted out of plant materials. These oils are used in a wide variety of applications, such as perfumes, cosmetics, cleaning products, and also for food and beverage flavourings.As widely acknowledged, due to its robustness and easy applicability, gas chromatography (GC) presents to be the most suitable characterisation technique. However, the significant cost per analysis and the large number of samples tobe analysed per-day, requiring faster response requirements, have highly increased the interest in minimising analysis time.
