Phases for Liquid Chromatography

The first step of system development is the choice of the mobile phase. While the use of neat solvents is preferred, very often, a mixture of solvents must be used to obtain good results. The selection of the mobile phase should be based on  [Pg.118]

A two- or three-dimensional graph drawn with axes at right angles implies that each factor can take completely independent values and that a response exists for every point on the graph. This may be the case for many factors. If the effects of initial pH and time of an experiment are being studied, for example, it is probably acceptable to set the pH of the solution then allow the experiment to go for as long as required. However, if a simple water/ methanol mobile phase for liquid chromatography is used, it would be a waste of an axis to try to optimize both water and methanol concentration, because what is not water is methanol and vice versa. This is only a one-factor problem—the fraction of water (or methanol). [Pg.73]

The mobile phases that have been used most extensively to date are n-pentane and carbon dioxide. Pentane has the advantage that it is a liquid under ambient conditions, so that it can be handled and pumped in the same way as mobile phases for liquid chromatography. On the other hand, its critical temperature is relatively high (almost 200 °C) and it is a highly inflammable compound. [Pg.103]

The classical case of surface monolayers are the stationary phases for liquid chromatography. Dimethyloctadecylsilyl-modified silica (= Cig-silica) is a representative and popular member of the alkylsilyl silicas. From the supra-... [Pg.165]

Since the advent of liquid column chromatography, the desire of every chromatographer has been for a better stationary phase. The most common stationary phases for liquid chromatography are porous, rigid spheres (usually manufactured from silica, SiOa). Irregular or nonspherical particles... [Pg.233]

In Section 30D, we described some of the applications of ion-exchange resins to analytical separations. In addition, these materials are useful as stationary phases for liquid chromatography, where they are used to separate charged species. In most cases, conductivity measurements are used to detect eluents. [Pg.986]

The efficiency and selectivity of fuUerenes as adsorbents from aqueous solutions has resulted in a number of analytical applications of C g and C g as chromatography stationary phases, as chemical sensors and, especiaUy, as sorbents for the preconcentration of analytes. In the latter case, the adsorption properties of fuUerenes are more useful for inorganic and organometaUic compounds than for organic compounds. On the other hand, the fuUerenes exhibit a selectivity for aromatic compounds and planar molecules that makes them very attractive as stationary phases for liquid chromatography. [Pg.359]

The main principle of distribution liquid chromatography is the same as for gas chromatography as well. However, the stationary phase for liquid chromatography is in most cases a non-polar liquid. Non-polar stationary phase is called reverse-phase and the method used for chromatography with such a stationary phase is called reverse phase technique. [Pg.101]

It was indicated that most detectors used in high-pressure liquid chromatography are optical detectors that use ultra violet, visible or laser light sources. It stands to reason that the solvents that can be used as the mobile phase for liquid chromatography must have special properties. The most important properties of the mobile phase for high performance liquid chromatography are ... [Pg.105]
