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 ...

Anion sensing and detection in aqueous media have emerged as fundamental challenges and opportunities in environmental monitoring, biomedical diagnostics and industrial process control. Recent ...

Selective extraction of specific, charge-dense anions from a solution is beneficial, but has been limited in practice by the inability of anion extraction to overcome the Hofmeister bias. In ...

The anion gap blood test measures the acid-base and electrolyte balance in the blood. Results can show whether there is an imbalance in a person’s pH levels, which may be making the blood too acidic ...

A low anion gap results from an imbalance in the body’s pH levels. Healthcare professionals identify this “gap” by examining the results of a blood test that measures electrolyte levels. To maintain ...

With the columns of the new Anion line, Hamilton sets new quality standards in the field of ion chromatography. The columns combine outstanding durability with high separation efficiency, guaranteeing ...

Efficient purification processes that separate impurities from air and water are necessary to sustain life on earth. To this end, carbon materials have long been used for deodorizing, separating, and ...
