This method helps them ascertain the drug's country of origion, which can help determine the distribution chain.

The University of Technology (St. Andrew, Jamaica) has received a multi-million dollar donation of lab equipment from Johnson & Johnson (Canada).

Capillary flow technology (CFT) devices are microfluidic components that extend capillary GC capabilities through simple and robust connections between pressure/flow modules and columns. One of the most powerful and simple is the CFT Tee. This is especially useful in GC–MS analysis providing (1) rapid column and inlet maintenance without MSD venting and (2) the capability of rapidly removing late eluting interferences from the column by forcing their retreat into the injection port through "backflushing". Removing these interferences improves column and detector longevity and analytical integrity. Backflushing is very valuable for trace GC–MS analysis in samples from complex matrices like soil, foods or tissues. The CFT Tee uses pressure-pulsed injections and constant flow mode with minimal loss in the MS signal. This approach will be useful to all GC–MS users who want to improve their instrument uptime.

A new APCI/APLI source enables a high resolution TOF-MS to be coupled on LC and GC, thus increasing flexibility and performance of TOF-MS in combination with GC.

Over the last 10 years, several solvent-free microextraction techniques for gas chromatography (GC) and mass spectrometry (MS) have been developed. Two of these techniques, solid-phase microextraction (SPME) and stir-bar sorptive extraction (SBSE), are available commercially for the analysis of volatile compounds, such as flavors in foods and beverages, and toxic organic compounds in environmental applications. Other techniques, such as open tubular trapping, inside needle capillary adsorption trap (1), in-tube SPME, capillary microextraction, needle trap, and headspace solid-phase dynamic extraction (2), were also developed for different applications. The basic principle for all of these techniques is essentially the same. Volatile and semivolatile compounds are adsorbed on a sorbent coating, often packed on the interior surface of a capillary column or stainless steel needle. After the sample is concentrated on the coating, the compounds are desorbed thermally in the heated injection port of a gas..

Illegal drug use worldwide is at an all-time high. There is a crucial need for fast and accurate analysis to positively identify suspected drugs in criminal investigations. Gas chromatography combined with time-of-flight mass spectrometry (GC–TOFMS) can be a valuable tool for drug testing in forensic crime laboratories. Method development and GC–TOFMS experimentation was conducted in cooperation with a local crime laboratory. The laboratory testing presented will illustrate highly efficient methods and data developed for crime labs that assist in the battle against illegal drugs. Many drug classes have chemical properties that present particular analytical challenges, such as poor detector response, chemical lability, or poor chromatographic peak shape. This article presents GC–TOFMS methods developed for several major drug classes and chemical functionalities. The major drugs included in the initial method development are methamphetamine, ecstasy, and heroin. Robust and accurate..

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 more.

OI Corp (College Station, Texas), a provider of a variety of technologies in the chemical analysis field, has entered into an agreement with DANI Instruments SpA (Cologno Monzese, Italy), a developer of GC instruments and accessories.

Nysa Membrane Technologies, Inc., announced Natrix Separations, Inc. as the company's new name.

Agilent Technologies Inc. has announced that it has hosted the first of three leadership delegations from China's Anti-Doping Agency, as China prepares for the 2008 Olympic Games.

Successful gas chromatography (GC), akin to many other disciplines, requires regular attention to a number of routine procedures. Chromatographers, similar to anyone else, develop habits in their daily work. Some of these help create a successful laboratory environment, while others can be ineffective or worse, can create more problems than they solve. This month, "GC Connections" presents a few of the best and worse laboratory habits.

The authors present results that suggest that high-throughput, high-coverage profiling capabilities, such as those afforded by GCxGC-TOF-MS, can impact the development of personalized medicine.

Separations Systems Inc. Honored at White House

Northeastern University Researcher Receives International Honors

Thermo Fisher Scientific Inc., the world leader in serving science, announced that they have been presented with two 2008 Frost & Sullivan Best Practices awards for Market Leadership and Competitive Strategy Leadership in Informatics.

In the first reported study of skeletal muscles in hibernating creatures by two-dimensional gel electrophoresis (2-DE), scientists from Korea have attempted to shed some light on the molecular processes behind atrophy prevention.

Scientists in China have devised a GC-ECD procedure that involves bromination of acrylamide to give a derivative that is more easily detected at low levels than acrylamide itself. Their research comes in response to the discovery of acrylamide in many types of cooked food in 2002. This discovery made news due to the link between acrylamide and cancer. From a scientific point of view, the acrylamide discovery ensured the creation of a new generation of research grants, many of which involve mass spectrometry, using GC?MS or LC?MS.
