In a study of sampling, ions have been extracted from a variety of flames and analysed mass spectrometrically. For this, a flame sample was expanded continuously and supersonically into a vacuum, and an ion beam formed for mass analysis. Observations of ion currents for various pressures in the firs

It is shown that when a flame is sampled supersonically, cooling of the sample can occur in two regions: the boundary layer on the high pressure side of the sampling orifice and also in the subsequent supersonic and near-adiabatic expansion into the vacuum chamber. It is possible to divide such a sa
