DEVICE FOR RESEARCH Phase Transfer Kinetics of exchange in the 'gas-solid' With the analysis of the isotopic composition of gas phase

摘要

The utility model is aimed at carrying out studies using deuterium exchange, disposal of the oil and water vapors in a gas circuit, no diffusion difficulties during puffing test gas into the ionization chamber of the mass spectrometer, the expansion of the working pressure range. The apparatus comprises a mass spectrometer with a measured range of mass numbers from 1 to 200 amu, connected to the gas circuit placed in the warmed casing and connected thereto reactors, and equipped with a three-stage, oil-free vacuum system for evacuating the gas at high loop vacuum. 1 n.p.f. 1 yl.
