  • Reagent and method for detecting an adulterant in an aqueous sample
    Patent number: 6303384
    Abstract: This invention relates to a reagent and use of that reagent for detecting adulterants in aqueous samples, particularly in biological specimens such as urine samples using a diazo dye precursor such as N,N diethyl-1,4-phenylene diamine and a reagent such as creatinine to stabilize a colored intermediate formed by the reaction of the diamine with nitrite ions for a period sufficient to allow that color to be recorded and compared with a separate peak formed by a halogen-based oxidizing agent which may be present in solution.
