You won’t feel a thing: Detecting anions in a single drop of blood

Date: Jul 13, 2015

Author: Jon Evans

By developing a way to conduct ion chromatography on a single drop of blood, chemists from Japan and the US have been able to follow how the concentrations of two physiologically important anions fluctuate over a couple of days.

Just add water: A novel electrodialytic ion exchange device

Date: Jun 8, 2015

Author: Jon Evans

Water is the only requirement of a novel electrodialytic ion exchange device that can suppress the eluent from ion chromatography and then subsequently regenerate it.

Nutty ion-exchange behavior: Why doesn’t phytate elute when it should?

Date: May 11, 2015

Author: Jon Evans

The discovery that the phosphorus-storage molecule phytate elutes strangely in ion-exchange chromatography could help improve the separation of highly-charged analytes.

Journal Highlight: Hierarchical CaCO3 chromatography: A stationary phase based on biominerals

Date: Apr 27, 2015

Author: separationsNOW

Japanese chemists have developed a novel chromatography stationary phase for separating acidic small organic molecules, which is made from biominerals derived from scallop and sea snail shells and starfish skeletons.
