中国科学院上海冶金研究所研制成功的FDT-1 型光纤双波长光度滴定仪已通过专家鉴定。该所科研人员把光导纤维、光电探测二极管等先进技术与传统容量分析技术结合起来,制成本仪器。所研制的仪器灵敏度高,使容量分析可应用于微量元素的测定,测定范围可达4—5个数量级,准确度和精密度高,由于采用了双波长光路设计,使仪器有较强的抗浊度能力,与微机相配可实现分析
FDT-1 optical fiber dual-wavelength photometric titrator successfully developed by Shanghai Institute of Metallurgy, Chinese Academy of Sciences has been certified by experts. The researchers made optical fiber, photodiode and other advanced technologies and traditional capacity analysis technology, made this instrument. The developed instrument has high sensitivity so that the capacity analysis can be applied to the determination of trace elements. The measurement range can reach 4-5 orders of magnitude with high accuracy and precision. Due to the dual wavelength optical design, the instrument has strong resistance Turbidity capacity, matched with the computer can achieve analysis
