ABSTRACT:
A method of detecting gluteraldehyde adulterant in a urine sample. An aliquot of urine is inserted into an automatic chemical analyzer and a spectrophotometric absorbance reading is taken. Thereafter, the aliquot is mixed with a reagent mixture containing a carbonyl indicator and a second spectrophotometric absorbance reading is taken and compared to the first reading.
