Curiosity To Finish Arm-Work Phase This Week
September 10, 2012 9:42 am | by NASA | News | CommentsAfter driving more than a football field's length since landing, NASA's Mars rover Curiosity is spending several days preparing for full use of the tools on its arm. Curiosity extended its robotic arm last Wednesday in the first of 6-10 consecutive days of planned activities to test the 7-foot (2.1-meter) arm and the tools it manipulates.
Antimicrobials From Personal Care Products Found in Rivers, Lakes
September 10, 2012 9:40 am | by Arizona State Univ. | News | CommentsA science team has completed the first statewide analysis of freshwater bodies in Minnesota, finding widespread evidence of the presence of active ingredients of personal care products in lakes, streams and rivers. Hundreds of antimicrobial products are sold in the U.S., many marketed with efficacy claims that remain elusive due to the short duration of the average consumer’s handwashing practices.
Researchers Optimize Photoluminescent Probes Using Spectroscopy
September 10, 2012 9:38 am | by Rice Univ. | News | CommentsNew research offers a methodology to optimize the sensitivity of photoluminescent probes using time-resolved spectroscopy. The technique gives results nearly twice as good as standard fluorescence spectroscopy when probed for specific DNA sequences.
Chromatography Market to Reach $8.9 Billion in 2017
September 10, 2012 9:36 am | News | CommentsThe global chromatography market was worth USD $6.6 billion in 2011 and is expected to reach USD $8.9 billion in 2017, growing at a CAGR of 4.1% from 2011 to 2017. The chromatography market is driven by growing environmental and safety concerns, rise in crime rate, safety and security of human life and rise in the number of cancer diagnosis.
Fish Ear Bones Provide a Living History
September 10, 2012 9:34 am | by Woods Hole Oceanographic Institution | News | CommentsUsing gas chromatography, researchers measured compounds in otoliths of individual fish, working their way back to layers created when each was a juvenile. The method analyzes isotopic signatures recorded in fish tissue. These signatures, unique to each environment in which a fish lives and feeds, are laid down in its otoliths, or ear bones, creating a record similar to that of tree rings.
Device is First-Ever to Measure Mass of a Single Molecule
September 10, 2012 9:31 am | by CalTech | News | CommentsA team led by scientists at the California Institute of Technology has made the first-ever mechanical device that can measure the mass of individual molecules one at a time. This new technology will eventually help doctors diagnose diseases, enable biologists to study viruses and probe the molecular machinery of cells, and even allow scientists to better measure nanoparticles and air pollution.
Gold, Silver Nanoparticles Act As Biofuel Catalysts
September 10, 2012 9:29 am | by Argonne National Laboratory | News | CommentsResearchers have been successful in synthesizing and characterizing monodisperse gold-core silver-shell nanoparticles utilizing a bio-template that has potential as a water soluble catalyst for converting biomass, such as dead trees, branches and tree stumps, yard clippings, wood chips, and even municipal solid waste into fuels.
Chromatography Techniques: September 2012
September 5, 2012 2:39 pm | Digital Editions | CommentsCheck out the digital edition of Chromatography Techniques' September 2012 issue. The cover story details gas chromatography systems used on Mars, and those used on Earth as well. Other articles detail with detection spectroscopy, clean gas, time-of-flight and solid phase extraction.
Automated and Semi-Automated Sample Prep
September 5, 2012 12:52 pm | by Tim Studt, Editorial Director | Articles | CommentsChromatography itself can be used as an automated sample preparation procedure for sample purification in drug discovery. Automating solid phase extraction (SPE) is also increasingly useful for rapid sample prep and purification for chromatographic or other analyses.
Extracting for Health
September 5, 2012 12:46 pm | by Christina Smith, Editorial Intern | Articles | CommentsSolid-phase extraction (SPE) is one of the most common chromatographic processes, and, in recent years, the growth of automated SPE has catapulted its use in laboratories. As a result, SPE systems are becoming more integrated—being made more compatible with liquid chromatography mass spectrometry (LCMS) systems, or combined with LCMS in one system.
TOF-MS Takes on Complex GC Analyses
September 5, 2012 12:27 pm | by David Barden, ALMSCO International, Llantrisant, UK | Articles | CommentsThe latest advancements in time-of-flight mass spectrometry have allowed the technology to easily tackle day-to-day analysis of complex samples by GC. On the face of it, time-of-flight mass spectrometry (TOF-MS) ought to be more popular than it is.
The Art of Raman Spectroscopy
September 5, 2012 12:17 pm | by Thomas Tague Jr., Bruker Optics, Billerica, Mass. | Articles | CommentsNew capabilities such as advanced detectors and optics are improving the use of infrared and Raman spectroscopy in the chemical analysis and validation of art objects. The analysis of art objects is conducted for a variety of purposes, with authentication being the most visible.
Clean Gas Yields Clean Chromatography
September 5, 2012 12:05 pm | by Agilent Technologies | Articles | CommentsThe need for good gas hygiene is important to avoid risking the integrity of instruments, as well as to produce better, more productive chromatography. Ensuring gas hygiene is one of the most important steps researchers can take to optimize the performance of GC or ICP systems. Impure gases can cause installation delays, premature instrument failure and flawed results.
GC on Mars (and Earth)
September 5, 2012 11:51 am | by Tim Studt, Editorial Director | Articles | CommentsNASA's Curiosity rover has a compact GC system for analyzing rocks, while new GC systems on earth work with increased sensitivity and accuracy. The automated sample analysis at Mars (SAM) module is just one of a dozen instruments contained in NASA's Mars Science Laboratory (MSL) that are mounted on the Curiosity rover that landed successfully on Mars on August 5.
