近年来,国内外已在离子选择电极自动化分析技术上迈出新的一步。国内在分析工作及工艺流程中广泛使用了离子选择电极分析技术,并应用了快速注入续流电极测定技术,但适用于地球化学分析的离子选择电极自动分析技术尚未见报道。我们在原有快速注入续流电极测定的半自动分析基础上,改进进样系统,采用程序控制自动进样,清洗管路及测定。带有微处理机的高级离子计则可直读浓度。在没有条件的地方仍可用校正曲线法计算结果。也可根据资料的介绍加装前置比例放大器,反对数放大器及
In recent years, at home and abroad have taken a new step in ion-selective electrode automation analysis technology. Domestic analytical work and process widely used in ion selective electrode analysis technology, and the application of rapid injection freewheeling electrode determination technique, but for geochemical analysis of ion selective electrode automatic analysis technology has not been reported. On the basis of the semi-automatic analysis of the original fast-injection free-wheeling electrode assay, we improved the injection system and used program-controlled autosampling to clean the tubing and determine. Advanced ion counters with microprocessors read the concentration directly. In the absence of conditions can still use the calibration curve method to calculate the results. According to the introduction of information can also be installed pre-proportional amplifier, anti-logarithmic amplifier and
