Oven Program: 40°C, 0.5°C/min. Carrier Gas: Hydrogen, 180kPa (best conditions with Helium carrier gas is 300kPa pressure).

Sample:

!Real sample with 95-97% of Bornyl Acetate and 3-5% of Isobornyl Acetate and a extremely high abundance of the “S” enantiomer of Bornyl Acetate. The sample was diluted 1µL/1mL in n-Hexane.
