Research into the environment takes place all over the globe. Having the ability to perform immediate analysis in remote locations can make or break a research project. Robust IC systems have allowed researchers to continue their analysis in some spectacular locations, from the Southern Ocean to the edge of the...Read More

Learning to work in the laboratory can be a tough process for both student and teacher. Teachers want to give their students the best experience without damaging expensive research equipment. Students want hands on experience with all of the technology on offer but lack the experience with which to handle...Read More

Acid etching baths are used for oxide removal and cleaning of the surface of different types of steel. To keep the bath in an optimum condition the Fe2+/Fe3+ and free acid/total acid ratios must be maintained within certain limits. Auxiliary substances like hydrogen peroxide are added to influence the Fe2+/Fe3+...Read More

As the connection between adverse health and the species of chromium, arsenic, perchlorate, and selenium are becoming clearer, analytical requirements are becoming more stringent. Detection limits are getting lower and speciation is becoming more important. So much more than halide analysis Combining the separation of IC with detection techniques such...Read More

The market has spoken and we have listened. Faster, Safer, Easier, Smarter, More than ever before. Metrohm's titration platform is modular and can be expanded from a simple stand-alone titrator to a powerful robotic system performing 4 analyses simultaneously processing up to 175 samples completely unattended. Multiple work stations that...Read More

Aluminium is used everywhere: in automobiles, bicycles, soft drink cans, cookware, and is even found in most antiperspirants, yet it does not occur in a natural state. Aluminium is a reactive base metal, and is mainly refined from bauxite ore, which contains approximately 60% alumina (Al2O3). To smelt aluminium directly...Read More

Nitrogen in wastewater is mostly organic nitrogen. The importance of nutrient removal in the form of nitrogen and phosphorus in industrial and municipal wastewater has increased significantly over the past decade to minimize water pollution and avoid eutrophication of water bodies. Nitrogen in wastewater is mostly organic nitrogen, ammonium/ammonia and...Read More

Today, sugar in foodstuff  has become a major health related topic. Stricter limitations and more specific labelling requirements are being introduced. Metrohm's Application Note P-62 "Sugars and sugar alcohols in an apple drink applying pulsed amperometric detection" is just one example of Metrohm sugar analysis solutions.Read More

Preparing roasted coffee bean samples for Near infrared spectroscopy analysis: NIR is used to determine coffee quality, components and for authentication. The advantages are that it is a chemical-free assessment, fast, non-destructive and reduces labour-cost. The diversity of foodstuffs with their often very different product properties represents a real challenge...Read More

Mercaptans (thiols) and hydrogen sulfide (H2S) Fossil fuels are known for their sulfur content, which originates from the decomposition of dead organisms over millennia. Mercaptans (thiols) and hydrogen sulfide (H2S) are two sulfur compounds present in crude oil which contribute to its characteristic odor. In the refining process, these can...Read More

The new ASTM method D8045 demonstrates the superiority of thermometric titration for complex petroleum samples, as it provides for better reproducibility of results, is significantly faster, and consumes less reagent than the commonly used method D664. This method requires no sensor maintenance aside from a solvent rinse, needs no hydration...Read More

Amines have been used for many years to remove acid gases from natural gas. Amine systems have been the workhorse of the gas treating industry for many years and the push is harder than ever for optimum performance and reliability. Along with proper maintenance of equipment, proper care of the...Read More
