WebThe popularity of the technique is due to Headspace analysis providing a clean, reliable result. Dramatic improvements in sensitivity are achieved with the new Dynamic Headspace option, while maintaining the ruggedness … WebMultiple headspace extraction (MHE) is an absolute quantitative method used in static headspace—GC. In principle it is dynamic gas extraction, carried out stepwise and establishing equilibrium conditions in each step. The concentration of the analyte in the headspace decreases exponentially during the series of extraction steps: by proper …
WebHeadspace is a technique used to introduce volatile components of a sample into a gas chromatograph (GC). The matrix typically is not amenable to direct injection into the GC system. Examples are liquids and solids such as lotions, blood, soil, polymers, even electronic components.
