采用USEPA方法OIA1677和FlowSolution®IV测量有效的氰化物
这里描述了按照USEPA方法OIA-16771-4，通过价位交换、流动注射分析(FIA)和安培计检测有效氰化物的方法。这个方法用于USEPA关于清洁水法案，资源保护与回收法案，全面环境响应，补偿与责任法案和安全饮用水法案的数据采集和检测程序，采用这个方法检测水中的氰化物离子(CN-)、氰化氢(HCN(aq))，以及相关锌、铜、镉、汞、镍和银的氰络合物。氰化物广泛应用于电镀和金属采矿操作过程中。它们也应用于合成纤维和塑料的生产，并作为除草剂和农业化学物质。氰化物按照清洁水法案1的307(a)(1)节，是法规限制的毒性污染物，是来自于毒性污染物列表2中的主要污染物。OI分析仪器公司的Flow Solution Ⅳ(FS-Ⅳ)，是一台高分析能力的自动离子分析系统，并且采用FIA技术应用于这个方法。采用增强的扩展范围(ER)TM检测技术，允许一条校准曲线扩展到3-4个数量级，这样明显减少了超标样品必须重复分析的次数。系统的WinFL......阅读全文

什么是－Flow－Chemistry－？
flow chemistry 一般译作 流动化学。本意指在连续流动的系统中完成化学反应，不同于批次式反应。其实流动过程中完成化学转化的生产方式并不独特，早已广泛用于石化工业和 合成氨、硫酸、盐酸、硝酸等大化工领域。真正让流动化学独具魅力的是 小型化 和 智能化。流动化学不仅仅单纯指物料的流动，而是结

Joe－Flow的流变学小课堂
温度控制：加热和冷却“今天，我想跟大家谈谈温度控制在流变测量中的重要性。要了解温度对样品流变特性的影响程度，只需测试同一个校准过的标准样品在不同温度下的粘度值就可以了。即使两次测量之间温度仅相差 1 ℃，都会导致 7 % 的粘度值变化。因此，地温度控制极其重要。”01哪种温控设备适合哪个温度范围？
