我目前就找到这些,希望有知道的话,不妨也把它贴上来,好让大家多了解CFA连续流动分析的理论!呵可!

您讲的CFA英文没有错，但把SFA（间隔流动分析）的技术解释为CFA（连续流动分析技术），概念上可能有问题。真正CFA法也是有应用的，是无气泡间隔的，也不需流动注射过程的流动分析技术，流动分析技术中还有顺序注射技术等，而间隔流动分析技术才是采用气泡间隔测试的流动分析技术。

美国TCHNICON公司好像也不是现在的B&L公司，而是TCHNICON将其认为不赚钱的流动分析仪器部门卖给了B&L公司，其本身还有机械手等部门。

楼上的似乎很懂,不妨发表一些高见,不过我不知你说的TECHNICON把认为不赚钱的流动分析仪卖给了B+L公司是啥意思?你想要说的是AA3不是CFA吗?那么请问CFA仪器品牌您请举个例子看看行吗?另外您所知道的关于TECHNICON卖给B+L的历史说说看?抑或您是哪个品牌的CFA代表,也不妨说一下您的仪器的优点,大家一起探讨,从您回的几个贴子看,您很了解CFA或SFA及FIA,不妨一一说说,另外您说的蒸馏器之事,我想一并在此说明:安装时要加硅油,当然可以看到拆卸和安装玻璃管件,因此并非您所说的安装时就要拆卸,因此只要客户在场第二次加硅油是不会费时和费事的!

TECHNICON公司同B—L的关系及历史您问您工厂的人就清楚了，这是香港东南（以前TECHNICON的总代理商）的早就清楚的。流动分析按分类上有SFA（间隔流动分析）品牌有SKALAR，BURKARD，B——L，阿利安斯等；FIA（流动注射）品牌有LACHAT，FOSS等；SFA/FIA可同机实现的是OI公司的。蒸馏器加硅油只是
一种蒸馏器的简单方法，相当于油浴，补加硅油，自然是有拆装过程，安装调试时无此过程，但一般也不会告知用户怎麽拆装，用户用到时才会谈到。自然用根本就不需加硅油的要好。

您可能对CFA同SFA的定义不清，建议您仔细考虑这两个概念的差别。真正的CFA应用中OI公司的既有。

嗯!不错,原来是OI公司的大虾,原以为你有很多高见,不过为了个CFA和SFA,FIA的几个概念在争,你想说AA3或别的什么品牌是SFA或CFA,等等什么都行,不过我想在目前,在自动化学仪这一行,我知道FIA的LACHAT做得不错,在环境监测行业AA3和LACHAT都做得不错了,,在啤酒行业嘛,不说你也知道是荷兰的SKALAR和B+L的AA3,,至于阿里盎司在土壤和农作物方面有特点,当然OI也有特点主要是在血液检验方面,现在AA3在疾控行业、自来水行业、烟草行业的业绩有目共睹，特别是烟草行业的标准大多以其分析方法做为行标，目前水行业也出了一些关于连续流动分析方法的标准，不妨请大虾也去瞄瞄！

至于AA3的历史，我所听到的与大虾所说有点点出入，我只知道当时的TECHNICON所在的化学分析仪部份卖给B+L公司时，有部分员工不愿意从美国离开，转而在美国继续做后来并入了现在的OI公司自动化学仪器部门。至于SKALAR和阿里盎司，在此不想说，只是大虾提到了历史不妨也说说OI的自动化学仪历史，因此您说的把不赚钱的卖给了B+L公司，那么OI的。。。。。。

我是烟草行业定标的亲历者，我觉得B——L把几乎每个品牌都参与的标准制定工作说成是自己的工作，不知是谁讲给您的？您分析的行业市场状况好像也有问题，您最好了解清楚后再讲。您既然讲课给大家，就有必要讲清：连续流动分析；间隔流动分析；流动注射分析等基本概念，免得让人从根本上搞不清您要讲的内容。
