PACS Advanced GAED Testing

Whereas the American Society for Testing Materials (ASTM) iodine number is the most popular figure of merit for activated carbons, the present state-of-the-art is more powerful by at least an order of maginitude. One can now rapidly determine what amounts to a calibrating isotherm (`correlation curve`) on a carbon, and then compute, for that carbon, the adsorption isotherms of a wide variety of gases/vapors or solutes from water solution, from traces to saturation, using software available from Professional Analytical and Consulting Serivces Inc. (d.b.a. PACS).
