Scope
HG/T 4199-2011 is the English-translated version of 无机化工产品中氟含量测定 离子色谱法.
HG/T 4199-2011 is the Chinese chemical industry standard for determining fluoride in inorganic chemical products by ion chromatography. It gives the terms and definitions, the general rules, the principle of the method, the operating principle of the instrument and its flow diagram, the interferences, the reagents and materials, the apparatus, the analytical procedure and the calculation of results. The method serves for the fluorine content of inorganic chemical products, over a determination range from 0.05 mg/L to 100 mg/L of fluoride expressed as F. Laboratory water follows GB/T 6682-2008, and the general analytical rules of HG/T 3696.2 and HG/T 3696.3 apply. The Chinese classification is G10. Issued on 20 December 2011, it has applied since 1 July 2012.
