The work described in this paper was performed as a part of the evaluation of a method for the determination of organic halides in water by carbon adsorption. Specifically, this paper presents data acquired during the routine use of an organic halide analyzer. Results were evaluated for repeatability, precision, and accuracy. The instrument's measurements of organic halides were compared with measurements of trihalomethanes by the purge-and-trap method. The measurement's dependability and problems associated with sample storage are considered in this paper. (Abstract also appears in Spanish) Includes 6 references, tables.
