Winters in Scandinavia were long and cold in the Bronze and Iron Ages, then as now— but a blazing fire was not the only thing to keep people warm. From northwest Denmark, circa 1500-1300 BC, to the Swedish island of Gotland as late as the first century AD, Nordic peoples were imbibing an alcoholic grog.
While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life.
Research has suggested that human earwax— an easily obtained bodily secretion— could be an overlooked source of personal information.
Topological insulators are the key to future spintronics technologies. Scientists have unraveled how these strange materials work, overcoming one of the biggest obstacles on the way to next-generation applications.
Researchers have timed plasmon-generated electrons moving from nanorods to graphene.
Researchers are using a unique method of nanomaterial imaging to more effectively determine the highly variable acid leaching values of Western Australian nickel laterite ores.
Researchers have developed a relatively low-temperature process to convert certain kinds of plastic waste into liquid fuel as a way to re-use discarded plastic bags and other products.
Scientists have discovered the bonds in a buckyball can be “detuned” when exposed to an electric current in an optical antenna.
Scientists have together developed a new, inexpensive material that has the potential to capture and convert solar energy— particularly from the bluer part of the spectrum— much more efficiently than ever before.
Scientists have created a way to fine tune a process critical to the pharmaceutical industry that could save a lot of time and money.
The February issue of Chromatography Techniques features articles on mutiple residue pesticides, ancient wines and beers, 2-D HPLC, design innovations, whisky drinks, and more.
Tosoh Bioscience’s TSKgel High Temperature (HT) and Ultra-High Temperature (HT2) GPC Columns are designed for gel permeation chromatography and size exclusion chromatography (GPC/SEC. The release of these columns is accompanied by the EcoSEC High Temperature GPC System for polymer analysis up to 220 C.
Designed to make it quick and easy to choose the right pH electrode for any laboratory application, the Thermo Scientific Orion pH Electrode Selection Guide is an interactive guide that helps the user select the most appropriate pH electrode to meet their indicated needs and budget.
Phenomenex has published its updated product and services guide for 2014/2015. Covering the company’s lines of HPLC/UHPLC columns, GC columns, SFC columns and sample preparation products, this year’s catalog highlights many new offerings, including a Yarra analytical dimension and prep column and an Aeris Peptide 2.6µ column.
Chromatographic separations of proteins are based on their difference either in size (size exclusion chromatography), electric charges (ion exchange chromatography), or hydrophobicity (reversed-phase chromatography).
Waters’ ACQUITY UPLC M-Class System is a nano- to microscale UltraPerformance LC (UPLC) system rated for 15,000 psi operation. Coupled to proprietary mass spectrometers, the system delivers the sensitivity to quantify and identify very small concentrations of key molecules.
Metrohm’s series of IC systems includes the high-performance 940 Professional IC and the smaller, but just as reliable, 930 Compact IC Flex. These versatile ion chromatographs are self-monitoring and feature unlimited configuration possibilities that are able to meet specific analytical requirements.
Scientists using gas chromatography can enjoy a number of options with the Thermo Scientific TRACE 1300 Series GC system, designed to conserve helium, permit use of multiple detectors simultaneously, automate sampling gas workflows and perform flame photometric detection.
Global researchers are working together to develop methodologies to identify pesiticides in food with triple quadrupole chromatography systems.
Minot Analytical’s CE (capillary electrophoresis) system, from Prince Technologies, offers high efficiency separation for both small and large molecules with a choice of internal diode array and external modular detectors.
Mott precision porous metal flow restrictors are reliable, cost-effective replacements for orifices, capillaries or micrometering valves. Product designers can be assured of a constant gas flow at a given gas pressure without having to worry about clogging and without having to design for wide variations in flow.
