    你用的哪种仪器?可以显示浓度?显示的就是离子浓度对么?能简单说一下你用的测定方法么?

    wxbyj 发表:电位和浓度都可以直接显示.你讲的对我很有用,在此谢过.

    英国的仪器,直接显示浓度,原理就是电位测量方法,事先做好标定,直接将电极放入待测溶液即可.

    进口的有自动稀释的装置。利用加液器的原理。

    当然,也有更好的含自动进样器全自动的稀释滴定一体化的全自动电位滴定仪,连续测定高含量的氯离子没有任何的问题。

    我们提供的自动稀释是进口的,为大仪器配套时才用,2.5/24000的精度,可通过软件任意操作稀释和进样.可多个样,也可多步稀释,价格可能不适合你.

    先发个简单些的关于全自动稀释的装置吧。全英文的,希望能有所帮助。瑞士万通的产品。

    Metrohm 846 Dosing Interface - intelligent dosing
    Pipetting – transferring – diluting – dosing – dispensing
    The 846 Dosing Interface and the 800 Dosino turn the basic liquid handling operations into child's play. The 846 Dosing Interface is a control unit for up to four dosing elements. It can be used to expand existing Metrohm systems but also deals, as an independent system, with any liquid handling task occurring in the laboratory.

    Thanks to the straightforward and unrestricted programming of the dosing elements even the most complex liquid handling tasks in the range 10 µL to 100 mL can be performed with high accuracy and precision.

    Advantages of automatic versus manual liquid handling
    Sample preparation needs less time
    The results are independent of the operator
    Reagent consumption is lower, which means less waste and less waste removal costs
    Improved dosing accuracy and precision
    Fully automated dosing setups can be configured


    Amazing possibilities!
    The 846 Dosing Interface is USB-compatible and fits perfectly into existing Titrando and automation systems, which can thus be equipped with additional dosing elements.

    The 846 Dosing Interface can be controlled with an 840 Touch Control, as an independent system, or via PC. Control by PC offers two possibilities, namely tiamo™ or the PC Control software. Whatever type of control you choose, all of them are compatible with the FDA Regulation 21 CFR Part 11.

    The 846 Dosing Interface is equipped with four MSB ports allowing to connect 800 Dosinos, 805 Dosimats, stirrers, etc. in the same way as this can be done with a Titrando or Sample Processor.
