The LVSH6 solution from Entech is a next generation Large Volume Static Headspace (LVSH) technique that uses the SPR40 autosampler to carefully and quantitatively transfer the equilibrated  headspace above a liquid or solid sample through an ASP Sorbent Pen in order to measure the composition of the equilibrated headspace. This equilibrated headspace is what a consumer experiences when they open a container of facial cream, or open a food package, or even when they apply a fragrance to their skin. Virtually all other headspace techniques perform extractions,  leaving the fixed gases behind (air, nitrogen, etc), or they add more fixed gases to the headspace to flush compounds to an external sorbent, but in both cases the equilibrium is disturbed which ends up providing a compositional analysis of the liquid or solid sample, not what a consumer would be smelling. Stated another way, if a SPME extraction of a typical 10mL vial were to be  performed over a 10-20 minute period to try to improve the sensitivity of the method, and then this fiber were desorbed into another inert container so that all compounds would be in the gas  phase, the resulting aroma will almost certainly be different than what was present in the original, equilibrated headspace. As long as headspace is pulled from the container without being replaced  by additional gases, the equilibrium that has been set up at a given temperature will not be affected very much, especially if we only collect about half of the volume of the vial. With a 1L  vial where 900cc is headspace, that would be 450-500cc of fully equilibrated headspace, and when using a splitless injection technique, this could provide low to even sub part per trillion detection  limits on some GCMS analyzers. This provides aroma/flavor/fragrance chemists with a whole new approach for “seeing what their customers are smelling”. Knowing the composition in the liquid or  solid is only half the challenge. Unless the partition coefficient for each compounds in each matrix is known ( an near impossible task), the headspace at equilibrium must also be determined  experimentally. That is what LVSH offers. Therefore, VASE to measure the composition of the liquid or solid samples, and LVSH to measure the equilibrated headspace concentrations. The LVSH6  module along with the volume measurement capabilities of the SPR-FM add on module makes the entire process automated for six 1L vials.
