We have considered the features of the supersonic underexpanded flows formation under conditions of developed condensation, as well as measurements in such jets by electron-beam and molecular-beam methods. It is shown that under the conditions of large clusters formation both the geometry and the structure of supersonic jets may change. It is determined that the use of a mass-analyzer for recording monomers and clusters in a molecular beam has a number of peculiarities caused by the molecular beam formation from a jet containing large clusters. A method of mass spectrometry of clustered flows during the ionization of gases in a jet before the formation of a molecular beam is proposed. The features of this method are illustrated.
