A simple and fairly standardized technique of extracting volatile and semi-volatile substances from raw samples in liquid or solid form is headspace analyzes. A sample is placed in a vial that is sealed by a septum and cap and heated in an incubator for a specific time. Once the content of the vial has reached equilibrium a sampled is extracted and injected into the injection port of a GC. LEAP’s specific equipment the CTC COMBI PAL performs all the tasks for this extraction method unattended. For a sequence of samples up to 96 the COMBI PAL will schedule the vials to be in the incubator/agitator for the same amount of time before a precise sample of headspace gas is extracted by a heated syringe system for a subsequent appropriate injection into a GC. Many variables are programmable over a validated range. 1ml, 2.5ml and 5ml syringes and a solvent-less solid phase micro extraction system are the tools that can be mounted in the injection head. | A simple and fairly standardized technique of extracting volatile and semi-volatile substances from raw samples in liquid or solid form is headspace analyzes.

Abstract
A simple and fairly standardized technique of extracting volatile and semi-volatile substances from raw samples in liquid or solid form is headspace analyzes. A sample is placed in a vial that is sealed by a septum and cap and heated in an incubator for a specific time. Once the content of the vial has reached equilibrium a sampled is extracted and injected into the injection port of a GC. LEAP’s specific equipment the CTC COMBI PAL performs all the tasks for this extraction method unattended. For a sequence of samples up to 96 the COMBI PAL will schedule the vials to be in the incubator/agitator for the same amount of time before a precise sample of headspace gas is extracted by a heated syringe system for a subsequent appropriate injection into a GC. Many variables are programmable over a validated range. 1ml, 2.5ml and 5ml syringes and a solvent-less solid phase micro extraction system are the tools that can be mounted in the injection head.
