The accuracy, precision, and reproducibility of a rapid method for determination of fluoride in wine, using a fluoride selective ion electrode, were established by a collaborative study involving 12 laboratories, 5 in Europe and 7 in the United States. The laboratories assayed 6 Youden pairs of fluoride-fortified, red and white wine samples with fluoride concentrations ranging from 0.2 to 3.0 mg/L. The relative standard deviations of repeatability ranged from 1.94 to 4.88%; relative standard deviations of reproducibility ranged from 4.15 to 18.40%. HORRAT values ranged from 0.30 to 0.97. The average recovery was 99.97%. Based on the statistical results of this collaborative study, the Study Director recommends that this method be adopted First Action.
一项采用氟离子选择性电极测定葡萄酒中氟化物的快速方法的准确性、精密度和重现性，是通过一项由12个实验室参与的协同研究确定的，其中欧洲有5个实验室，美国有7个实验室。这些实验室分析了6组尤登对的添加氟化物的红葡萄酒和白葡萄酒样品，氟化物浓度范围为0.2至3.0mg/L。重复性的相对标准偏差范围为1.94%至4.88%；重现性的相对标准偏差范围为4.15%至18.40%。HORRAT值范围为0.30至0.97。平均回收率为99.97%。基于这项协同研究的统计结果，研究主任建议该方法首次采用。
