All studies represented by the chromatogram below have been conducted utilizing Large Volume Static Headspace analysis on the 7650HS-CTS

The all-new 7650HS-CTS is the only commercially available solution that can quantify the consumer experience by taking an equilibrium “snapshot” of the headspace to accurately determine its composition from the lightest through the heaviest compounds. The 7650HS-CTS is truly unique as it is the industries “only” system that uses multiple stages of true capillary columns to perform headspace preconcentration.
