重油检测水分Z简单的方法？

     A Greenwich, Connecticut-based shipping company has purchased a VISCOfuel 2000 viscosity control system from Cambridge Viscosity.The VISCOfuel viscometer was installed on board one of their cargo ships this fall to monitorthe viscosity of heavy fuel oil (HFO) combustion.

Prior to the VISCOfuel, the cargo vessel had been running with a malfunctioning OEM viscometer.Without consistent viscosity control, the vessel had a number of maintenance issues including blocked injectors and inefficient combustion.The new VISCOfuel directly replaced the

original OEM viscometer without any modifications to the plumbing.Thechiefengineer and port engineer had worked with Cambridge’sVISCOpro system in the past,and came to Cambridge first because of their first-hand experience with the dependability,accuracyand robustness of the product.The upgrade was the first ofthe fleet, with additional upgrades planned in the near future.

     ''Cambridge Viscosity viscometers were selected because of their reputation in the industry as a superior productand the company’s rapid response tothe shipping company's installation schedule,''saysCambridge President Robert Kasameyer.The shipping company will integrate the VISCOfuel 2000 into a third-party controller alreadyon board the vessel to maintain the viscosity of marine fuel for proper combustion.

     Controlling the viscosity of heavy fuel oils has long been a challenge for the industry. In the past, machine operators maintained proper viscosity by controlling fuel oil temperature. This required establishing the proper temperature control set point toyield the correct viscosity for a given grade of fuel oil. Oil manufacturers developed viscosity vs. temperature tables for the various grades of fuel to assist operators in determining theproper set point.Theproblem with this method was that fuel oil viscosity/temperature tables were based on expected values for the various blends of heavy fuel, not the actual fuel oil batch that was to be burned.

    In reality, the viscosity index for heavy fuel blends varies considerably from batch to batch. These batch-to-batch variations of viscosity index make it impossible to maintain proper viscosity control with one specific temperature set point.The difficulties caused by the inconsistency of fuel can include emissions problems,excessive maintenance and the overall inefficiency of burning.

    The industry realized that not all heavy fuel oils are created equal and that in order to achieve optimal combustion, the variability of heavy fuel viscosity needed to be controlled. The result has been the successful use of inline viscometers, the‘cruise control’ of heavy fuel viscosity management.

   Operators simply enter a control set point and the viscometer maintains it even if the viscosity index of the fueloil supply increases (up hill) or decreases (down hill) compared to the specification.The Cambridge viscometer used by the shipping company operates on patented electromagnetic-based sensor technology that analyzes the piston's two-way travel time to provide a direct measure of fuel oil viscosity. The VISCOfuel 2000 also features software designed specifically for fuel oil combustion applications.

至2012年的毒胶囊事件后，人们对药物的质量安全意识越来越浓，对其质量检测的要求也越来越高，在胶囊的生产过程中，水分含量是一个重要的控制指标，胶囊水分含量的高低会直接影响其质量和使用期限，甚至会直接影响包含其中的药品的质量和使用期限。

上海禾工AKF-2010HT卡尔费休医药专用水分测定仪与市场同类产品相比，禾工AKF-2010HT高精度水分测定仪在胶囊样品不能完全溶解的情况下，采用加热搅拌台辅助样品加热溶解，精确的检测出其样品的含水量，测试过程更加的安全、环保、方便。

方法步骤：

1.使用仪器的“吸溶剂”功能向滴定池内注入约40ml的无水甲醇溶剂。

2.使用仪器的“打空白”功能滴定至终点，以去除滴定池内的水分，仪器就绪并保持终点的状态。

3.用经过干燥处理的微量进样针精确抽取10ul纯水，拭干针头后放入天平称量，将前后两次称量之差作为纯水的重量输入到仪器，开始标定。

4.重复步骤3，反复测量3-5次，仪器会自动保存标定结果并计算出平均值作为试剂的滴定度。

5.用加样针抽取一定量的样品加入滴定池，将进样前后加样针的重量之差作为样品进样量输入仪器，并开始测量。
