The analytes entering the headspace above a sample are removed, trapped and concentrated, therefore equilibrium between the headspace and sample is never reached. Dynamic headspace is more sensitive than static headspace, as the whole headspace volume can be removed and concentrated prior to analysis, although the additional trapping parameters must also be optimised.
