title: Determination of bromide ion concentration in greyhound urine by ion chromatography.
abstract: An ion chromatographic method was used to determine Br ion in the urine of Greyhounds. Phenol was added to the urine, before filtration through a 30,000-molecular weight cutoff filter and to the eluant (pH 11, NaOH-Na2CO3), as a preservative. Urine from 103 racing Greyhounds resulted in a mean +/- SD of 3.60 +/- 2.72 mg of Br/L of urine. Urine samples obtained from a Greyhound, to which 2 g of KBr was administered, yielded a diurnal elimination pattern with a half-life of 7.6 days.
