Total Fluoride Analyzer The Model 9000F Total Fluoride Analyzer from Antek Instruments, Inc. offers a safe, quick, and cost effective instrumental method for determining the total fluoride content of gas, liquid, and solid samples. An alternative to the hazardous Wickbold method (oxyhydrogen torch) and other time consuming wet chemical procedures, the 9000F provides answers within minutes instead of hours. It is far less expensive than ICP/MS and, unlike tape methods, the Antek 9000F is specific for fluoride without interference from other halides. Typical analysis time is less than ten minutes. Analytical range is from ppb to percent levels. Complete instrument control and data processing are provided by a 486/66 computer with Windows software package included. Software features include real time results, single- or multi-point calibration, data storage and manipulation. Applications include: LPG, fluoro-polymers, alkylates, catalysts, petroleum products, additives, refinery feedstocks, toothpaste, and physiological samples (blood, bone, and tissue). This technology is also available for process/on-line applications. tometrically by absorbance at 525 nm. The detection limit was determined at 5 ppb in meat and in animal feed and at 2 ppb in urine. Advantages of using this method are (1) positive identifica" tion in biological samples, (2) quantitative determination, and (3) high sample throughput at low operating costs.
