提供溶劑自動制備系統(tǒng)哪里有 提供溶劑自動制備系統(tǒng)供應
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：對于大多數送到分析實驗室的樣品來說，溶液制備是步操作。準確的溶液制備和存貯是整個分析過程的基礎。PhasePrep系統(tǒng)專門為此而設計。
Automatic Internal Standard Addition—Save Time, Reduce Costs
中文：全自動、內標法添加-節(jié)省時間、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、氣相、AA、質譜色譜等技術中，獲得高精確數量的*傳統(tǒng)方式是根據已知濃度的物質來標定未知濃度的物質，也就是傳統(tǒng)的內標法。未知物質的濃度可根據測試結果與濃度經過標準地、精確測量的物質相比較而得出。

The phasePrep Solution Preparation System saves labor while increasing accuracy when preparing solutions having an internal standard.
中文：Phaseprep 溶液制備系統(tǒng)通過內部的標準既可以提高準確性，又能夠減少勞動量。
The PhasePrep does this in five labor saving steps:
通過以下五個步驟來實現(xiàn)
樣品轉移，在瓶上打印標簽。
Gravimetric Dilution: More Accurate than Volumetric1. Operator enters the sample number ａnd his/her initials.
操作人員可輸入個人姓名的首字母作樣品編號。

2. A sample bottle is placed on the balance ａnd the computer records the weight.
電腦能夠測量、記錄樣品瓶重量。
3. Operator is prompted to add the appropriate amount of solute to the bottle.
操作人員將近似重量的溶質添加到樣品瓶中。
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%.
電腦可計算出所需溶劑的準確質量。將溶劑加入到樣品瓶中所得到的稀釋溶液精確度為0.02%。
