Testing | GAEDagglomerating thermoplastic binder significantlyloses some of its physical adsorptioncapacity. We have previouslydemonstrated that it is possible to separateGAC particles touching the binderfrom free particles trapped in the blockand run the particles on GAED to determinethe lost pore volume over the adsorptionenergy range.GAED example reports are availableat www.pacslabs.com. Note that thesereports provide more information thanpresented in this article due to spacelimitations. Some additional informationare: GAED provides temperaturevs. loading capacities, BET surface area,pore diameters, differential adsorptioncurves, trace- and mid- capacity data, arange of other compound adsorptivities,and a quick market survey for newsorbent types of possible applications.CONCLUSIONMany applications 2 for GAED testingare available. Recently GAED was used toreveal the carbon filters that would be bestto replace a municipal drinking waterplant 4 that uses parallel GAC absorbentsto provide a blended water supply.ACKNOWLEDGMENTThe authors credit Dennis B.
