Chromatography is the science of separating molecules of interest to identify, quantify or even purify them. Properties of the target molecules such as their solubility, size or hydrophobicity give ...

Rising drug costs have increased public pressure on the biopharmaceutical industry to find ways to identify and eliminate high-cost unit operations. Biopharmaceutical manufacturing groups now ...

Ion exchange separates components in a sample depending on their relative ionic strengths and interaction with the stationary phase. The stationary phase is a charged substance that selectively ...

The term liquid chromatography (LC) refers to a class of physicochemical methods which are used to separate and quantify compounds in a sample. LC is made up of a liquid mobile phase, which carries ...

In this paper, the authors introduce a method that combines ion exchange chromatography with an easier-to-perform, simpler one-step post-column derivatization that is selective to nitrite and visible ...

This course will present an overview of the state of the art in ion-exchange process chromatography: development, scale-up and optimization of preparative chromatographic processes. The attendees will ...

RECENT years have seen the development of many new techniques of importance to the chemist ; of these, chromatography and ion-exchange have received special attention of late. A well-attended ...

In a year that will long be remembered for financial losses, plant closings, wide-scale cutbacks, and layoffs, analytical instrument maker Dionex managed to grow. In its past fiscal year, which ended ...

Chromatography is a technique that is used for separation of mixtures. The name combines the Greek word chroma, or “color,” with graphein, “to write.” The technique was invented in 1900 by Mikhail ...
