Claim 1
Independent Claim
80 words
A METHOD OF ANALYZING AN AQUEOUS SOLUTION CONTAINING A VERY SMALL QUANTITY OF A REDUCIBLE SUBSTANCE TO DETERMINE THE CONCENTRATION OF SAID REDUCIBLE SUBSTANCE, COMPRISING IRRADIATING SAID SOLUTION WITH A LOW-INTENSITY PULSE OF RADIATION CAPABLE OF PRODUCING HYDRATED ELECTRONS THEREIN, SAID SOLUTION HAVING A PH OF 11 TO 12 AND HAVING BEEN SATURATED WITH HYDROGEN, PASSING A BEAM OF LIGHT THROUGH THE SOLUTION, AND COMPARING THE CHANGE IN TRANSMISSION OF THE LIGHT AS THE HYDRATED ELECTRONS DECAY WITH A STANDARD.
