Ion chromatography is used to determined concentrations of ionic species in a test sample by isolating them according to their interaction with a substrate. The technique divides ionic species based ...

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 ...

Ion exchange chromatography (IEX) is a versatile and widely used technique for separating biomolecules based on charge. It plays a critical role in protein purification in research and ...

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 ...

Maintaining high levels of drug quality and safety is priority for the pharmaceutical industry. Pharmacopoeias have documented these standards as officially acknowledged pharmaceutical rules.

Choosing the right eluent is essential for high-performance ion chromatography (IC). In IC, the eluent works in tandem with the column and analytes to achieve accurate separation. This is ...

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 ...
