钙黄绿素EDTA萤光络合滴定法现已广泛应用于合金中高镍的测定,近年来有人试验了光电自动控制终点及程序自动滴定的装置.本文研制的AFT高镍萤光自动滴定仪,能自动进行定量加液、自动滴定、自动光电终点判断和数据处理,能在3分钟内将试样的含镍百分浓度数字直读,适用于合金中含量在20～80%的镍进行定量分析.此外,仪器还能求取滴定度T以及体积比系数K,同时还具有延时终点判断功能,
Calcein EDTA fluorescence complexometric titration has been widely used in the determination of high nickel alloy, in recent years someone tested the end of automatic control of electro-optical devices and automatic titration device.This study developed AFT high-nickel fluorescent auto-titrator, automatic Quantitative dosing, automatic titration, automatic optical end-point judgment and data processing, the sample can be within 3 minutes of nickel content concentration direct reading digital, suitable for quantitative analysis of the nickel content of 20-80% in the alloy. In addition, the instrument can also obtain the titer T and the volume ratio coefficient K, but also has the delay end judgment function,
