- Scope
- A small quantity of the oils is analyzed under specified conditions. The alpha- and beta-thujone contents are determined by using the internal standard or addition method. As stationary phase are used cyanopropyl methylphenyl methyl silicone, or trifluoropropylmethyl silicone, or polyethylene glycol 1500. Operating temperatures: Oven: isotherm about 100 鳦 when using cyanopropyl methylphenyl methyl silicone or trifluoropropylmethyl silicone; isotherm about 130-鳦 when using polyethylene glycol 1500. Injection system and detector: about 170 鳦.
