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 ...

In literature, the terms “ion exchange chromatography” and “ion chromatography” (IC) are often used interchangeably, thanks to the wide use of IEX, and refer to the separation of polar or ionic ...

In a recent study published on the medRxiv* preprint server, researchers assess the ability of gas chromatography-ion mobility spectrometry (GC-IMS) to differentiate between coronavirus disease 2019 ...

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 ...

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 ...

Gas chromatography–ion mobility spectrometry (GC–IMS) is a recent technique applied to food flavor analysis – including the evaluation of food freshness, processing of food products, and changes in ...
