Column Chromatography:In this sort of chromatography, the stationary phase, as well as the mobile phases are kept inside a given column. The disassociation of the sample takes additional time here. HPLC:This stands for High Performance/Pressure Liquid Chromatography. It is a more updated variant ...
The driving force of a liquid chromatography separation is determined by solute partitioning between the mobile and stationary phases. Chromatographers must study a wide range of mobile-phase compositions and stationary-phase bonding densities to determine the thermodynamic driving force. The author ...
to a surface (the stationary phase) which is used to separate the mixture components while moving through the stationary phase with help of the mobile phase. There are four general chromatography types: gas chromatography, thin-layer chromatogra...
Question 6.11:What criterion is followed for the selection of the stationary phase in chromatography? 相关知识点: 试题来源: 解析 The stationary phase is selected in such a way that the components of the sample havedifferent solubility's in the phase. Hence, different components have different ...
-Supercritical fluid chromatography (SFC) In this post I will focus on flash chromatography, the principles of which are the same as HPLC. Both use columns filled with a stationary phase into which sample is injected and through which solvent is pumped. However, flash chromatography uses larger ...
Describe a practical application of chromatography, and give an example that is unrelated to photosynthesis. We have mentioned that chromatography has many applications. Research one application of chromatography and explain how it is used and what characteristic is utilized for...

chromatography can be either anion-exchange or cation-exchange. In cation-exchange chromatography, the stationary phase is negatively charged in order to attract the positively charged ions. Conversely, anion- exchange chromatography uses a positively changed stationary phase to attract the negatively ...
The stationary phase of the affinity chromatography contains the core, spacer, and ligand. Sometimes, it also has a metal ion that is coupled to the ligand. The most preferred solid phase for the stationary phase in this technique is agarose gel because it is easily dispensed to fill and p...
The Chemistry Dictionary tells you what a chromatography column is and what it does. A chromatographic column is a tube packed with a stationary phase to separate mixed components. It consists of column tube, pressure cap, ferrule (sealing ring), sieve plate (filter disc), joints, screws, etc...
