提供溶剂自动制备系统哪里有/原装溶剂自动制备系统报价
1. Solution preparation is the first operation that has to be performed for the vast majority of samples that are submitted to an analytical laboratory. Accurate solution preparation ａnd documentation is, therefore, the foundation for the overall integrity of any analytical laboratory. The Design Scientific PhasePrep System is designed specifically for this purpose.
中文：对于大多数送到分析实验室的样品来说，溶液制备是第一步操作。准确的溶液制备和存贮是整个分析过程的基础。PhasePrep系统专门为此而设计。
Automatic Internal Standard Addition—Save Time, Reduce Costs
中文：全自动、内标法添加-节省时间、降低成本。
The most common way of obtaining high quantitative accuracy in HPLC, GC, AA, Mass Spectrometry ａnd other techniques is to spike an unknown concentration of a sample with a known amount of another substance—commonly known as an internal standard. After the sample is analyzed, the response to the unknown concentration is compared to the internal standard ａnd an accurate measurement of the concentration of the substance of interest is obtained.
中文：在高效液相、气相、AA、质谱色谱等技术中，获得高精确数量的最传统方式是根据已知浓度的物质来标定未知浓度的物质，也就是传统的内标法。未知物质的浓度可根据测试结果与浓度经过标准地、精确测量的物质相比较而得出。

The phasePrep Solution Preparation System saves labor while increasing accuracy when preparing solutions having an internal standard.
中文：Phaseprep 溶液制备系统通过内部的标准既可以提高准确性，又能够减少劳动量。
The PhasePrep does this in five labor saving steps:
通过以下五个步骤来实现
样品转移，在瓶上打印标签。
Gravimetric Dilution: More Accurate than Volumetric1. Operator enters the sample number ａnd his/her initials.
操作人员可输入个人姓名的首字母作样品编号。

2. A sample bottle is placed on the balance ａnd the computer records the weight.
电脑能够测量、记录样品瓶重量。
3. Operator is prompted to add the appropriate amount of solute to the bottle.
操作人员将近似重量的溶质添加到样品瓶中。
4. The computer calculates the exact amount of solvent required.The solvent, with the internal standard dissolved, is added to the sample to obtain a dilution with a typical accuracy of 0.02%.
电脑可计算出所需溶剂的准确质量。将溶剂加入到样品瓶中所得到的稀释溶液精确度为0.02%。
