Abstract

A review with 24 refs. The use of synthetic polyelectrolytes as displacers in displacement chromatog. is reported. Column liq. chromatog. is one of the main techniques of protein purifn. The majority of the present chromatog. biosepns. are performed in elution modes which have various disadvantages aside from economy. An attractive method to overcome the limitations of the elution mode is operation in the displacement mode. However, in order to exploit the full potential of displacement chromatog., suitable displacer/stationary phase systems must become available. The use of polyelectrolytes as displacers is believed to occupy an outstanding place. [on SciFinder (R)]

High-performance liquid chromatography

High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out of the column.

Iterative method

In computational mathematics, an iterative method is a mathematical procedure that uses an initial value to generate a sequence of improving approximate solutions for a class of problems, in which the n-th approximation is derived from the previous ones. A specific implementation with termination criteria for a given iterative method like gradient descent, hill climbing, Newton's method, or quasi-Newton methods like BFGS, is an algorithm of the iterative method.

Chromatography

In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed. Because the different constituents of the mixture tend to have different affinities for the stationary phase and are retained for different lengths of time depending on their interactions with its surface sites, the constituents travel at different apparent velocities in the mobile fluid, causing them to separate.
