Abstract
An experimental setup created on the basis of an infrared Fourier spectrometer and intended for an analysis of ultrasmall impurities in liquids and gases is described. Results of experimental studies of the vapor of ultrapure ammonium and nonsymmetric dimethylhydrazine are reported. It is shown that the limiting mole concentration of the detected impurities amounts to about (3–9)·10−4% for different types of gases.
