1. A system for determining a change of saturation of an adsorbent (111) susceptible to adsorption of species in an adsorption chamber (20), the system comprising:
a cage (110) made of a ferrite material and holding the adsorbent (111) therein;
a cage holder (112) configured to hold the cage (110) within the adsorption chamber (20) such that the movement of the cage (110) at least in a first axis is restricted to a smaller extent than in a second axis;
an exciter (120) comprising a coil (121) arranged at the cage, wherein the coil is connected to a voltage generator (122) and the exciter (120) is configured to induce eddy currents within the cage (110) resulting in oscillation of the cage (110) in the first axis;
a spectrum analyzer (125) connected to the coil (121) and configured to analyze the voltage within the coil (121) and determine its frequency response; and
a saturation detector (126) configured to determine the change of saturation based on the change of the frequency response determined by the spectrum analyzer (125).
