Gas Chromatography and Breathe Safely While Using Nitrogen
Gas Chromatography and Breathe Safely While Using Nitrogen Gas chromatography is a process used to separate chemical compounds for analysis. The analytical chemistry process is used with gases that won't decompose when vaporized. Gas chromatography are used in a wide range of industries -- everything from forensic science to medical marijuana. While the procedure is highly useful, there are risks when working with nitrogen gas. Learn how gas chromatography works, the role nitrogen plays, and how an oxygen sensor...
The first monitoring well in Engbertsdijksvenen is a reality
On Wednesday 20 December 2017, the first monitoring well of the groundwater monitoring network Engbertsdijksvenen was realised on the parcel of landowner Wilharms in Vriezenveen. This monitoring well serves to monitor the effects of the measures required for the Nature Objectives of the Engbertsdijksveen. One of these goals is the recovery of living high moor. In addition to this monitoring well, Eijkelkamp Soil & Water will also install 58 other monitoring wells within a radius of approximately 1.5 kilometres...
Reservoir Management - Online Oil-In-Water Monitor - Case Study
Background Older generation online oil-in-water (OiW) monitors may suffer from fouling of optics due to scales, soaps, emulsions, sludge, etc., resulting in inaccurate (usually low) concentrations. New generation OiW monitors: Yield more accurate O iW concentrations Improve accuracy of the OiW measurements, allowing operators to optimize water treatment systems so that more product is recovered and less is re-injected or discharged into the environment. Reduce operator maintenance and recalibration...
Researchers use `global thermometer` to track temperature extremes, droughts
Large areas of the Earth`s surface are experiencing rising maximum temperatures, which affect virtually every ecosystem on the planet, including ice sheets and tropical forests that play major roles in regulating the biosphere, scientists have reported. Earth`s Maximum Temperature Profile: Histograms of global annual maximum land-surface temperature capture the unique influence of different land-cover types on the expression of maximum land-surface temperatures. Tracking shifts in the distribution of these...
Monitoring for the golden balance
On Herøya in Porsgrunn, Yara has an ammonia plant, three nitric acid plants and a calcium nitrate plant. Together the plants produce a wide range of fertilizers that meet the requirements for fertilization of crops under varying climatic conditions and on different soils. Half of the production at Porsgrunn goes to overseas markets, mainly in Asia. The rest goes to Europe. – Our plants also produce a wide range of gases and chemicals for industrial use, says Karina Aas, Chief Engineer in the technical...
