A system and method for detecting the presence of contaminants in supercritical fluid. The system is based upon the use of an absorbent module comprising an absorbent which selectively absorbs the contaminant being measured and wherein the electrical properties (i.e. conductance and/or capacitance) of the absorbent varies depending upon the amount of contaminant absorbed. A sample stream of the supercritical fluid is contacted with the absorbent material. By measuring the electrical properties of the absorbent, contaminant levels are measured and monitored.
