When people talk about greenhouse gas (GHG) emissions, the focus is usually on carbon dioxide or methane. These two gasses make up about 90% of the GHGs that cause climate change. But there are a number of others that climate scientists monitor. Among them is sulfur hexafluoride, or SF6, a colorless, odorless gas used as an insulator in power substations. Though its prevalence in the atmosphere is small, it has the potential to make an outsized impact. Thats because it is the most potent GHG, with 23,500 times the global warming potential of carbon dioxide.Researchers in the power and energy sector where it is used have devoted significant effort to finding replacements.

Principles Various gas sensors measure the gas concentration inside the measuring head. Software calculates the flux directly on site. Accurate GPS module determines the exact location of the measurement.

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

Since their domestication millennia ago, nonhuman animals have been considered property. As such, they are often identified using various methods, including branding, that indicates their belonging to a certain ranch. Branding is used as a property stamp identifying the stockbreeder as the owner of the animal. By branding the animals, ranch owners are expressing the animals’ legal condition as mere things, or as slaves. There are many types of branding, including:

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.
