Melamine is an industrial chemical with a high nitrogen content that can cause kidney stones and lead to renal failure. In some instances, melamine has been added to baby formula and dairy products as a substitute for protein. This paper presents an efficient and definitive gas chromatography–mass spectrometry (GC–MS) method to identify melamine and related compounds based on the released US Food and Drug Administration (FDA) method.
This application details a fast, reliable and highly selective trace-level screening method for the quantification of polychlorinated biphenyls (PCBs) in environmental, food and biological samples, using gas chromatography and a triple stage quadrupole mass spectrometer. The analytical strategy is analogous to the well-established US Environmental Protection Agency (USEPA) Method 1668A.
Researchers Edward Staples from the US measurement technology company Q&A Solutions (Westlake Village, CA) and Shekar Viswanathan from the National University (San Diego, CA) have developed a new method for detecting contraband in cargo containers using urface acoustic waves (SAWs) and a capillary-based gas chromatograph column.

In this installment of "GC Connections," John Hinshaw addresses some of the more frequently asked questions he encounters about hydrogen as carrier gas.
A research group from Aristotle University of Thessaloniki (Thesaloniki, Greece) analyzed royal jelly, an important bee product, fortified with nine pesticides.
Celebrations for JASCO's 50th anniversary in the analytical instrumentation market will conclude with Jasco Europe, a subsidiary of Jasco Corporation, moving into its new facilities in Cremella, Italy in November 2008.
Teledyne Tekmar Company (Mason, OH), a subsidiary of Teledyne Technologies Incorporated, has partnered with Sun Analytical Instruments. Sun Analytical Instruments will be responsible for managing sales for Tekmar?s analytical instruments in Indiana, Kentucky, Michigan, Ohio, Western Pennsylvania and West Virginia.
According to a report in Nature News, nitrogen trifluoride is an extremely potent greenhouse gas used in the electronics industry, which is at least four times more abundant in the atmosphere than previously thought. Scientists recommend that to better control its use, NF3 should be added to the list of gases regulated under future climate-change agreements.
This month in "GC Connections", in the first of a two-part series, John Hinshaw relates what happens when high-voltage spikes attack modern electronic equipment, what to do when they occur, and how to set up equipment to minimize damage and loss of data.
Phenomenex, Inc., (Torrance, California) has been named one of the 15 best small workplaces in the U.S. by the Wall Street Journal.
Pittcon and Wiley-Blackwell announced that they will produce four webinars in 2008-2009 to kickoff the new "Wiley-Blackwell/Pittcon Webinar Series."
Thermo Fisher Scientific Inc. (San Jose, CA), t will host an informative seminar on the latest advances and applications for its vast range of GC products.
This month, Chromatography Online's Technology Forum looks at the topic of GC and the trends and issues surrounding it. Joining us for this discussion is Trisa Robarge of Thermo Fisher Scientific, Kaj Petersen of GERSTEL, and Sky Countryman of Phenomenex.
In this month's installment, Kurt Grob's life and achievements are described by someone who knew him like few other people did: his son, Koni Grob.
Researchers Philip Marriott from the RMIT University (Melbourne, Australia), Warawut Tiyapongpattana, and Prapin Wilairat from the Mahidol University (Bangkok, Thailand) have developed a 2D GC with FID method for determining the composition of biofuels that extends to the C4-C24 esters. They reasoned that a 2D separation, based first on boiling point then on polarity, would provide better resolution of the components.
