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(duì)于大多數(shù)送到分析實(shí)驗(yàn)室的樣品來(lái)說(shuō)，溶液制備是第一步操作。準(zhǔn)確的溶液制備和存貯是整個(gè)分析過(guò)程的基礎(chǔ)。PhasePrep系統(tǒng)專門(mén)為此而設(shè)計(jì)。
Automatic Internal Standard Addition—Save Time, Reduce Costs
中文：全自動(dòng)、內(nèi)標(biāo)法添加-節(jié)省時(shí)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(zhì)譜色譜等技術(shù)中，獲得高精確數(shù)量的最傳統(tǒng)方式是根據(jù)已知濃度的物質(zhì)來(lái)標(biāo)定未知濃度的物質(zhì)，也就是傳統(tǒng)的內(nèi)標(biāo)法。未知物質(zhì)的濃度可根據(jù)測(cè)試結(jié)果與濃度經(jīng)過(guò)標(biāo)準(zhǔn)地、精確測(cè)量的物質(zhì)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(guò)內(nèi)部的標(biāo)準(zhǔn)既可以提高準(zhǔn)確性，又能夠減少勞動(dòng)量。
The PhasePrep does this in five labor saving steps:
通過(guò)以下五個(gè)步驟來(lái)實(shí)現(xiàn)
樣品轉(zhuǎn)移，在瓶上打印標(biāo)簽。
Gravimetric Dilution: More Accurate than Volumetric1. Operator enters the sample number ａnd his/her initials.
操作人員可輸入個(gè)人姓名的首字母作樣品編號(hào)。

2. A sample bottle is placed on the balance ａnd the computer records the weight.
電腦能夠測(cè)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(zhì)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(jì)算出所需溶劑的準(zhǔn)確質(zhì)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%。
