The enantiomers of linalool and other important components of natural oils or natural extracts including cypress oil, geranium extract, balm leaves oil, and jasmin oil are separated on a multidimensional system using two separate GC ovens.The first oven is the conventional 7890 air bath oven equipped with a CFT deans switch and a 30 m × 0.25 mm × 0.25 μm DB-5ms, and the second is a direct heated LTM Ⅱ 5-inch module fitted with a 30 m × 0.25 mm × 0.25 μm CycloDex B chiral column.Use of independent temperature control for the chiral column allows for optimal separation conditions for linalool and other components in these natural materials.Full integration of LTM Series Ⅱ in the Agilent 7890A GC system enables operation in constant flow mode.Both FID/MSD and FID/FID systems are described.
