Performance Evaluation Software from Activated Carbon Services - PACS lets managers determine the loading capacity of specific contaminants on their carbons in air and water applications. This enables selecting the best carbon and amount to buy. The software is built on Polanyi-Dubinin-Manes-Greenbank publications for heterogeneous sorbent model-like activated carbons. Standard laboratory methods to provide carbon loadings can be costly, but software reveals capacity loadings more inexpensively. 724/457-6576; www.pacslabs.com
