Recently, a research team led by Professor HUANG Xingjiu at the Institute of Solid-State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has proposed a novel ...

Although the known photometric techniques for the calculation of ammonia are accurate, they take up a substantial amount of time (Nessler technique 30 min, indophenol technique 90 min reaction time).

Each year, lab technicians use ion-selective electrodes (ISEs) to make more than 1 billion measurements of ion concentrations in biological and environmental samples, according to industry estimates.

The number of ions belonging to different elements within a sample can tell a lot. In beverages and foods, different ions have specific limits established to ensure a minimum nutrient content is ...

Researchers have developed a new electrode for analyzing lithium ion concentrations. Unlike traditional systems, it could be manufactured in a small format at low costs. The key is the material ...

The number of ions belonging to various elements in a sample reveals a particular narrative. In foods and beverages, certain limits for various ions are established to protect health and guarantee a ...
