SV－2．0微机电极溶出仪的研制

The Development of SV-2. 0 Microcomputer Electrode Dissolve Out Analysis Instrument

本文设计和研制了ＥＣＡ电化学分析卡及ＳＶ－２．０型微机溶出仪及其软件，并进行了性能实验。ＳＶ－２．０是以３８６微机作为控制单元的汉化微机溶出仪。主要性能指标：检测限＜５×１０－１１ｇ／ｍ３镉，变异系数＜４％（１０×１０－９ｇ／ｍ３镉）；分辨能力为３５ｍＶ。主要功能有：自动谱峰检测；菜单提示；导数溶出；半微分溶出；非线性拟合；旋转电极系统；自动背景扣除；谱图缩放；高分辨显示及汉字打印；谱图束族功能。ＳＶ－２．０有中英文两种版本。

The main contents of this item investigation work are: The design and investigation for ECA electrochemistry analysis card. the investigation for the SV-2. 0 model software and the research of performance tests. SV-2. 0 is a mitro-computer dissolve out analysis instrument, and which control unit is the microcmputer of type 386. The main performance index: checking limit is less than 5 ×10-11g /m3 Cd: Precision is less than 4 % (10×10-9g/m3 Cd): distingisy rate is 35mV. The mum function: checking the peak antomatically; construction of ment inporting: printing report in chinese: control unit using 386 micro computer. derivative dissolve out: aemi-differential dissolve out, non-linear fitting: veraua electrode system: deducting the culvesa on the background automatically: lessen and enlarge function for drawing: shown with high resolution: print with high resolution: binding clan function for drawing. SV-2. 0 have both Chinese and English edition.
