摘要
介绍了北京吉天仪器有限公司开发的SA-10形态分析仪在测定砷形态和硒形态上的分析性能,大部分砷、硒形态的最小检测浓度小于1ng/mL。着重介绍SA-10形态分析仪在分析动物型海产品和植物型海产品中的砷形态以及在分析富硒营养品和富硒茶中的硒形态中的应用。
Performance of arsenic speciation and selenium speciation by SA-10 Speciation Analyzer developed by Beijing Titan Instruments Co., Ltd was discussed, The measurable concentrations for most of arsenic speciation and selenium speciation were all less than 1 ng/mL. The application of SA-10 Speciation Analyzer on arsenic speciation in animal and plant marine products and on selenium speciation in selenium nutritional supplement and tea was discussed especially.
