Abstract
The invention relates to a non-destructive method for determining the residual holding capacity of a given type of adsorbent filter, the adsorbent filter being capable of adsorbing a target gas, characterised by the fact that the method comprises the following steps: (a) choosing a probe gas and a carrier gas; (b) at given operating temperature, pressure and hygrometry, choosing injection parameters which comprise at least one sudden variation in the concentration of the probe gas in the carrier gas, for a given type of adsorbent filter, referred to as reference filter; (c) injecting the probe gas and the carrier gas into the reference filter according to the injection parameters, and measuring the change in the concentration of probe gas over time, downstream of the reference filter, for different known saturation rates of the reference filter, for an adsorbent filter referred to as the filter under test; (d) injecting, the probe gas and the carrier gas into the filter under test according to the injection parameters and measuring the change in probe gas concentration over time, downstream of the filter under test; (e) comparing the change in the concentration of probe gas for the filter under test and for the reference filter, in order to determine a value of the saturation level of the filter under test; and, (f) deducing the residual holding capacity of the filter under test.
