The active PA3 trap consists of a truncated cartridge containing a molecular sieve (adsorbant material) and 2 chimneys allowing air to be sucked through the cartridge.

Due to this geometry, the output of adsorption in the mass of tritiated water is homogeneous over the entire sieve and 100% (the tritiated water is totally trapped) up to a suction rate of 4 liters per minute.
