Dynamically - gravimetric method for determining the amount of gases or vapors, which in dense or porous solids are dissolved.

摘要

A method for determining the amount of a gas or vapor, which, in a dense or porous solid material is dissolved or adsorbed by means of simultaneous measurement of the apparent weight of the loaded with gas and is in a according to the working chamber, the sorption resonator, the solid with the aid of a balance, and the frequency of small, adiabatic vibrations of a test piece in the sorptivgas of the sorption resonator (reversal of the rüchhardt - test).In addition to the sorbed amount of gas, it is also possible for the volume of the gas-charged, rigid or pulsating solid be determined in the sorption resonator. These data are for the exact design and for the operation of technical sorption processes requires. Examples of such processes are adsorptive separation - and purification process for air and technical gases, adsorption - cold - and heat pumps processes and methods for novel porous substances.
