How does solubility affect chromatography
WebApr 14, 2024 · The solubility results did not show significant differences (p > 0.05) among all samples. However, maltodextrin showed the highest solubility for all ratios because the existence of OH groups in their molecular structure, through the interaction of hydrogen bridge bonds with the water molecules, makes them more soluble. WebThe solubility or viscosity of the sample may limit the quantity that can be applied to a column. High sample viscosity can cause instability of the separation and an irregular flow pattern resulting in broad, distorted peaks and problems with back pressure.

WebThe selection of chromatographic technique for refolding depends upon physicochemical properties of proteins such as solubility, hydrophobicity, iso-electric point, molecular weight and stability conditions (pH and temperature). From: Reference Module in Life Sciences, 2024 View all Topics Add to Mendeley About this page MEAT SPECIES DETERMINATION WebBecause a solute’s vapor pressure is smaller at lower temperatures, it spends more time in the stationary phase and takes longer to elute. In liquid chromatography, the easiest way to increase a solute’s retention factor is to use a mobile phase that is a weaker solvent.

As the liquid starts to move past the solid, some of its molecules (energetic things that are constantly moving about) are sucked toward the surface of the solid and stick there temporarily before being pulled back again into the liquid they came from. fnr bothmer
