Abstract
The present invention is directed to a method of assaying for the presence or absence of a metal-ligand chelate in a sample containing either a metal-ligand chelate or a free ligand. The method includes (a) reacting the sample with a luminophore to obtain either a metal-ligand-luminophore chelate and/or a ligand-luminophore adduct; (b) detecting the electromagnetic spectrum of the reaction product; (c) matching the electromagnetic spectrum of the reaction product with an electromagnetic spectrum metal-ligand chelate luminophore chelate or the electromagnetic spectrum of a ligandluminophore adduct; (d) correlating a match of the electromagnetic spectrum of the reaction product and the electromagnetic spectrum of the metalligand-luminophore chelate with the presence of a metal-ligand chelate, or correlating a match of the electromagnetic spectrum of the reaction product and the electromagnetic spectrum of the ligand-luminophore adduct with the absence of a metal-ligand chelate.
