Chromatography Efficiency and resolution Britannica

Chromatography Efficiency and resolution There are two features of the concentration profile important in determining the efficiency of a column and its subsequent ability to separate or resolve solute zones. Peak maximum, the first, refers to the location of the maximum concentration of a peak. To achieve satisfactory resolution, the maxima of two adjacent peaks must be disengaged.

Dispersion of NanoSized Alumina Powder in NonPolar

To disperse nanosized alumina powders in nonpolar solvents, the surface of alumina has to be modified with unsaturated oleic acid, which forms aluminumoleate on the surface. This changes the surface characteristics of alumina powders from hydrophilic to hydrophobic in nature.

Ordered Mesoporous Alumina with Ultra Large Pores as an

Alumina has recently turned out to be effective in enrichment of biomacrolecules like phosphopeptides due to its good affinity to phosphor groups. Ordered mesoporous alumina (OMA) materials with high surface areas, regular porous structures, and large pore size are an ideal absorbent for the enrichment of phosphopeptides. Herein, a ligand assisted solvent evaporation induced coassembly route
