The microwave digestion unit Speedwave Xpert is specially tailored to the needs of modern laboratories in which the highest degree of productivity coupled with easy handling is required. more
Researchers from Concordia's Department of Building, Civil and Environmental Engineering (BCEE) in collaboration with Bio-Terre Systems Inc. are taking the fight against global warming to colder climes. Their weapon of choice? Cold-loving bacteria. In a study authors Rajinikanth Rajagopal, David Bel more
Annual carbon emissions from global agriculture can be reduced by as much as 50 to 90 percent by 2030—the equivalent of removing all the cars in the world—according to a comprehensive new report released by Climate Focus and California Environmental Associates. The study highlights twelve key strate more
No more oil – renewable raw materials are the future. This motto not only applies to biodiesel, but also to isobutene, a basic product used in the chemical industry. In a pilot plant researchers now want to obtain this substance from sugar instead of oil for the first time. And in order not to threa more
Throughout the process of an analytical investigation, sample preparation - as opposed to the subsequent analytical steps - is the most time-consuming part. Excellent quality and extreme care during the process are essential for a functional analysis. The combination of high performance and carefull more
Over 35 years ago, Anton Paar developed the first digestion system with a nitrogen pressurized digestion chamber and pressure-sealed vessels – the HPA. Combining the HPA design with modern microwave digestion technology, the Multiwave 7000 represents the best way of acid digestion. Complete acid dig more
State-Of-The-Art Sample Preparation for Analytical Laboratories. Safe, Quick and Efficient more
In many analytical laboratories today microwave digestion is a standard method of preparing samples for determining elements. For microwave digestion the sample material is typically heated to 200 - 260°C in closed microwave-transparent pressure ves more
The efficiency of diluted acids for digestion of organic samples was tested as an alternative to common digestion procedures more
Which digestion methods are available for the control of elemental impurities in pharmaceuticals according to USP /? more
Field-grown rhubarb will shortly be coming into season and appearing in supermarkets in the UK, so it seems like a good time to take a look at the chemistry behind this odd-looking vegetable. It’s mostly used in pies and desserts, but it’s only the stalks of the plant that we eat – and there’s a rea more
In this work, an improved conductively-heated digestion system (CHDS) with closed-vessels, which provides simpler, easier and safer digestions of raw chicken, beef and pork meat samples aiming for Ca, Cu, Fe, K, Mg, Mn, Na, P, S, and Zn determinations by ICP OES and As, Cd, Cr, Mo, Pb and Se by ICP- more
In this paper, we explore a variety of aqueous digestion techniques for the determination of gold, in a wide variety of mineral matrices. These include feldspar, basalt, pyrites, and other gold-containing minerals. The acid-based digestion methods compete effectively with fire assay to deliver accur more
The environmental biorefinery consists in recovering and adding value to waste, possibly through a multi-product approach. A first implementation of such concept is the production of methane and nutrient-rich digestate by anaerobic digestion in biogas plants. However, methane and digestate have only more
Marcus von der Au, born in 1990, graduated from the University of Hamburg in 2016 in chemistry with a master's thesis in the department Marine Bioanalytical Chemistry of the Helmholtz-Zentrum Geesthacht. Since 2016, he has been working towards his doctoral degree in inorganic analytics under the sup more
