The trace heavy metal determination instrument is a kind of instrument which combines the method of using ise and isfet microsensors based on a sensitive chalcogenide glass with the method of the stripping voltammetry to determinate the trace metals in seawater 船载海水重金属元素现场自动分析仪是一种联合离子选择性电极检测技术和溶出伏安检测技术自动检测海水中痕量重金属元素的仪器。
Highlights of the applied research in 1997 included the analysis of volatile organics with canister sampling , carbon speciation of air particulates , semi - volatile organic pollutants in water , and ultra - trace heavy metals in sea water with on - linechelation 年内,化验所进行的研究计划,包括引用密封金属容器采样法,分析空气中挥发性的有机污染物;空气粒子中含碳化合物的类别分析;水中半挥发性有机污染物的测试;以及应用流线螯合法,对海水中超微量重金属进行定量分析。
The software system investigated in this thesis is used to control the trace heavy metal determination instrument to run the test and analyze data , the software system consists of several modules including data communication data preprocess pre - treatment respecting to real - time performance data storage , etc . the communication between the instrument and the server is based on serial port rs - 232 or ethernet port and the communication among the modules in the software system is based on the message mechanism in windows 并通过仪器对pb和cu混合溶液检测的实验,验证了联用多种算法可以自动对数据进行有效的处理。在对管理控制部分的论述中,文章研究分析了目前集群系统广泛采用的消息传递机制,并论述软件系统如何使用消息机制协调软件各个功能模块的运作。在系统与主机的通讯模块的设计中,文章论述了如何使用windowsapi函数实现系统的串行通讯接口和ethernet接口。
