Seminars address EU Water Framework Directive
A SERIES of seminars being held in European cities in 2012 will focus on the EU Water Framework Directive and the recent changes it has made to regulations covering water analysis across the continent. These have important ramifications for laboratories…
Faster tools for food safety and fish identification
A NEW project to verify the accuracy of food labelling, and to quickly identify strains of salmonella, will see Agilent Technologies develop new tests based on mass spectrometry and lab-on-chip techniques, under an agreement with the US Food and Drug…
Next-generation mass spec made simpler
IN A BID to boost adoption of its next-generation mass spectrometry technology, AB Sciex has launched a bundled package of instruments plus software, training, standards, and validation services. The Accelerated Lab Integration Package is launched to coincide with the launch…
Mass spectrometer is workhorse for routine operations
THE BEST-selling LC/MS/MS in history is how AB Sciex describes its API 4000, and so creating a replacement instrument is clearly not something to be undertaken lightly. The new 4500 series, unveiled this week at Pittcon 2012, is intended as…
Lab-on-a-truck makes US tour
YOU’VE heard of lab-on-a-chip, the incorporation of microfluidic circuitry into a sliver of silicon or plastic that promises to do to chemistry what transistors and integrated circuits did for electronics. At the other end of the scale we now have…
Signal/noise ‘no longer appropriate’ in mass spec
AGILENT Technologies has dropped the measure of signal-to-noise rario (S/N) from some instrument descriptions, saying that the measure is no longer meaningful. From now on, the company will cite the ‘ instrument detection limit’ specification for the 7000B triple quadrupole…
Agilent scores Virginia Tech deal
A MAJOR investment at the chemistry department of Virginia Tech will see several new Agilent instruments being installed in the university’s undergraduate teaching laboratories. Among the new tools are seven Agilent 5975C gas chromatography/mass spectrometry (GC/MS) systems, six 240FS atomic…
Ultra-sensitive mass spec for VOC analysis
PROMISING the highest performance and lowest detection limits for the detection of volatile organic compounds (VOCs) using proton transfer reaction mass spectrometry, the PTR-QMS-500 series from Ionicon is a new generation of ultra-sensitive PTR-MS online mass spectrometers. Detection limits lower…
First verified food allergen test by mass spec
WHAT IS said to be the world’s first commercial mass spectrometry method to detect and measure allergens in food has been launched by AB Sciex. The new Allergen iMethod application enables food testing labs to screen for egg and milk…
