Chromatography of charged analytes is often challenging as they are not retained effectively on the commonly used reversed phase columns and elute in the dead volume. On columns with polar or aqueous ...

Ion exchange (IEX) chromatography is a technique that is commonly used in biomolecule purification. It involves the separation of molecules on the basis of their charge. This technique exploits the ...

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

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 ...

Determination of sodium chloride level is critical for assessment of purity of yeast extracts. This case study demonstrates the validation of an ion chromatography method as a suitable analytical ...

In recent years, consumer awareness of food quality and ingredients has been on the rise. Consumers want to know more about what they eat and expect detailed information on the packaging to track this ...

The ion-trap LC/MS-MS instrument (Agilent XCT Trap) is our tool for confirmation of target compounds and study of fragmentation pathways. It provides MS n analyses and it has been successfully applied ...

Metal-organic frameworks (MOFs) have been recognized as an excellent platform for host-guest chemistry, which includes gas storage 1,2,3,4,5, ion-exchange 6,7,8,9,10 ...
