Monitoring mercury levels in ambient air is a crucial component of environmental protection, yet its widespread implementation has been fettered by the limited amount of global monitoring sites

Powerful batteries are key to the further advancement of green mobility and a decisive contribution to reducing carbon dioxide emissions. All over the world research laboratories are investigating materials and procedures to help increase the energy storage capacity and overall efficiency of batteries. Metrohm is pleased to support these efforts with an overview of analytical methods and dedicated applications used to analyze crucial parameters in battery research and production.

A new study demonstrates the feasibility of using attenuated total reflection Fourier transform infrared (ATR FT-IR) mapping for the identification of the prescribed and abnormal ingredients of herbal powder preparations (HPPs) for medicines.

HydraMist- Simultaneous Cold Vapor/Pneumatic Nebulization Spray Chamber The Glass Expansion HydraMist is a sensitive, simple-to-use spray chamber for Inductively Coupled Plasma (ICP) that allows simultaneous operation of both conventional pneumatic nebulization and cold-vapor/hydride generation. Cold vapor generation can provide more than 10-fold improvement in sensitivity on ICP for cold vapor forming elements such As, Sb, Se, Tl and Hg. The generation of volatile species of these elements results in increased analyte loading of the analytical plasma giving lower detection limits. The design of the HydraMist spray chamber is based upon Glass Expansion’s industry-standard cyclonic spray chamber, giving excellent sensitivity and short-term analytical precision with fast washout. The HydraMist spray chamber features a secondary inlet port that mixes the aerosolized sample and liquid reductant inside the spray chamber for rapid conversion of the As, Sb, Se, Tl and Hg analytes into volatile hydride species. The unique drain design ensures fast, complete removal of waste from the spray chamber, eliminating excess hydrogen build-up that causes sample reflux degrading analytical precision.
