ABSTRACT:
An automatic analyzer is used to determine out of range specific gravity of adulterants in a urine sample. An aliquot of the urine is mixed with a buffer and ion detector and thereafter with a polymer activator for ion detection. The mixture is analyzed by setting a spectrophotometer in the automatic analyzer at about 600 nanometers, setting the calibrating value for specific gravity at 1.000 and 1.0500 and reading a color change to determine the presence of adulterants.
