WebStir Bar Sorptive Extraction (SBSE), based on the patented GERSTEL Twister, is a fully established technique in the world of chromatography. Quite often, SBSE is simply the method of choice. WebThe extraction of the gases is achieved by agitating and heating the oil to release the gases into a 'head space' of a sealed vial. Once the gases have been extracted they are then sent to the gas chromatograph. Specialized techniques exist such as Headspace sorptive extraction (HSSE) or stir bar sorptive extraction (SBSE).
