国内第一家生产的双道原子荧光分析仪于11月30日在合肥通过技术鉴定。双道原子荧光分析仪是近几年发展起来的一种新的痕量元素分析方法,它具有分析灵敏度高,干扰少,线性范围宽,分析速度快等优点,目前已开始广泛应用于地质、冶金、环境保护、生物、医学领域。对一些易挥发元素如砷、锑、铋、汞、硒、碲等元素的灵敏度比原子吸收和电感耦合等离子光谱要高。该仪器双道同时测定基线稳定性小于满量程的正负千分
The first dual channel atomic fluorescence analyzer in China passed the technical appraisal in Hefei on November 30. Dual-channel atomic fluorescence analyzer developed in recent years, a new trace element analysis method, which has the advantages of high sensitivity, less interference, linear range, fast analysis, has begun to be widely used in geology, Metallurgy, environmental protection, biology, medicine. For some volatile elements such as arsenic, antimony, bismuth, mercury, selenium, tellurium and other elements of the sensitivity than atomic absorption and inductively coupled plasma spectroscopy is higher. The instrument dual simultaneous determination of baseline stability is less than full scale positive and negative thousand points
