Adsorption thermal response screening by optical adsorption calorimetry was recently demonstrated to be a versatile tool for rapid surface area and adsorption capacity testing of porous materials. Beyond the high throughput approach, further insight in possibilities and application examples for the method will be presented. Especially a rapid classification of porous materials regarding their pore properties and the possibility to evaluate adsorption kinetics by using thermal response measurements will be discussed. The temperature change of porous material upon exposure to a test gas (thermal response) can provide information about the adsorbent properties in a rapid way. Application examples for the prospective use of this novel method are given and discussed. The versatility of the ther mal response method as a screening tool for porous materials is demonstrated.
