Recent Research Demonstrates Determination of Total Phosphorus in Wastewater
News Oct 26, 2010
Dionex is pleased to announce the release of an application on the determination of total phosphorus in wastewater. Application Note 254: Determination of Total Phosphorus in Wastewater Using Caro’s Reagent and Ion Chromatography describes two IC methods, one with simple carbonate/bicarbonate eluent preparation and a second method that uses generated potassium hydroxide eluent and has the high reproducibility of an RFIC™ system.
Phosphorus in the environment is beneficial for many biological processes, but too much phosphorus can create an imbalance in the ecosystem. Monitoring the concentration of phosphorus in the environment is a good indictor because higher than normal concentrations lead to environmental problems. AN 254 demonstrates accurate measurement of the total phosphorus content of a wastewater sample using a Reagent-Free™ IC (RFIC) system with all its benefits, including excellent retention time reproducibility for accurate peak identification, and time and labor savings by eliminating eluent preparation and associated errors.

Understanding How Conditions Affect Environmental DNA AnalysisNews
Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, a team systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies.READ MORE
Surfers Three Times More Likely to Have Antibiotic-Resistant Bacteria in GutsNews
Regular surfers and bodyboarders are three times more likely to have antibiotic resistant E. coli in their guts than non-surfers, new research has revealed. The Beach Bums study asked 300 people, half of whom regularly surf the UK's coastline, to take rectal swabs. Surfers swallow ten times more sea water than sea swimmers, and scientists wanted to find out if that made them more vulnerable to bacteria that pollute seawater, and whether those bacteria are resistant to an antibiotic.READ MORE
