Resumen
Fluorometric method for the direct titration of nitrites/nitrates in serum and in biological tissue extracts. The titration of nitrites and nitrates is in increasing demand in both basic and clinical research laboratories. Some commercial fluorometric kits have the great drawback that they must be previously processed to eliminate interferences. The present invention describes a method for the titration of nitrites/nitrates for a concentration range of 0 to 1200 pmol of biological samples in a simple, direct way and avoiding the previous treatment of sample preparation to eliminate possible molecules that interfere in the result in other methods.
