The utility of a cationic polymer polyethylenimines (PEI) for coating some commercially available silica-based stationary phases packed in capillaries of 0.32 mm i.d. and 10 cm long was studied for ...

Thermo Fisher Scientific has announced a new Ion Chromatography (IC) , the Thermo Scientific™ Dionex™ IonPac™ AS18-4µm column for the fast analysis of inorganic anions in environmental matrices. By ...

This article shows how the requirements for the seven anions listed under part A of EPA methods 300.0 & 300.1, are effectively met using the Metrohm IC system. The calculated MDLs comply fully with ...

To date, there have been a plethora of reports on different means to fabricate organic–inorganic metal halide perovskite thin films; however, the inorganic starting materials have been limited to ...

Bambusurils, a class of glycoluril‐based macrocycles, have emerged as a unique subset of anion receptors owing to their robust and highly selective binding capabilities. These macrocycles feature a ...

All chemists are familiar with the litmus test. Like other acid-base indicators, litmus changes color when the pH of a solution changes. The indicator is an example of a "naked-eye" colorimetric ion ...
