The Selective Adsorption Analyzer SAA 8100 is a gas delivery system based upon the technology of PID Engineering and Technology, a Micromeritics company. The primary components of the system include mass flow controllers, blending valves, vapor sources, temperature control, and a simple column for evaluating adsorbents. The basic procedure for evaluating an adsorbent candidate includes: activation (degassing) of the adsorbent, flow a mixture of gases (or vapors) through the column containing the adsorbent, and monitor the composition of the effluent gas from the column containing the adsorbent.
