Figure 4.1. Experimental setup of a multipurpose instrument for coadsorption measurements of
multicomponent gas mixtures on porous solids. The instrument allows volumetric-
chromatographic, gravimetric-chromatographic and also combined volumetric-
gravimetric measurements for binary coadsorption equilibria.
Figure 4.2. Instrument for volumetric-gravimetric-chromatographic measurements of
coadsorption equilibria of gas mixtures on porous materials. The gas storage vessel
can be recognized on the left hand, the microbalance in the middle above the
thermostat and the gas chromatograph on the right hand side of the picture.
