| Abstract: |
| In the catalog, sorption isotherms are plottcd for more than 100 materials. Measured sorption values from different sources are put into a data base, and for each set of values the best curve through desorption and adsorption measuring points are fitted using the extended Posnow equation. A page of the catalog shows both data values and a figure with data points and approximated curves. An IBM PC has been used to build up the data base that is stored on a diskette marked SORPTION. The necessary data input and plotting pro-grams for the data base as well as programs for curve fitting of data points are also stored on the diskette. The programs have been discussed in a separate report where the execution of the programs is also described.
