答:HPLC(高效液相色谱)和GC(气相色谱)都是用来分析样品的组成和浓度的,它们都遵循同样的原理(色谱理论;定性定量原理;均可应用计算机控制色谱操作条件和色谱数据的处理程序):较重的分子会在洗脱、流动过程中慢于较轻的分子(极性也起着重要的作用)。同时,它们也存在着一些不同: A) 流动相的不同。GC:流动相为惰性...
research scientists at Schering Plough Institute developed this new technique. The key difference between HPLC and fast HPLC lies upon the pump pressure that we use for the separation. That is; the pump pressure that we use for HPLC is around 40...
8. Male mice germ-cell USD test: There was not significant difference between the UDS induced by different dose groups of water-decocted liquid of Zanthoxylum nitidum DC and that of negative control group. 三、雄性小鼠生殖细胞UDS试验:两面针水煎液各剂量组诱导的UDS与阴性对照组相比无显著性差异。
How to choose between HPLC or ultra-high-performance liquid chromatography (UHPLC) as they each have their own advantages and disadvantages
With the trend towards the use of smaller sub-2 渭m particle materials for analytical HPLC to run the analysis faster, one would also expect a move to these materials for purification. While high efficiency separations performed at speed are utilized for purification, the capital cost of high-...
High-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) are both commonly used techniques when it comes to separating components. Click to read more...
Difference Between Electrophoresis and Chromatography Difference Between Bromocresol Blue and Bromocresol Purple Difference Between HPLC and GC Difference Between Atomic Absorption and Atomic Emission Difference Between Sublimation and Deposition Filed Under: Analytical Chemistry Tagged With: Compare Percent Yield ...
Thekey differencebetween ODS and BDS column is thatODS column contains free –OH functional groups, whereas BDS column contains deactivated –OH groups. Reverse-phase HPLCis a chromatographic technique where we use ahydrophobicstationary phase. This stationary phase works well for the retention of mos...
The primary difference between HPLC and LCMS lies in their detection mechanisms and the information they provide. HPLC, while versatile in separation, relies on detectors that measure absorbance, fluorescence, or refractive index changes; it does not provide molecular mass information. LCMS, however, ...
The choice between GC and HPLC depends on the physical and chemical properties of the sample to be analyzed. 13 HPLC offers the advantage of analyzing a broader variety of samples because it does not require the sample to be volatile or thermally stable. It can be used with a wide range ...
