Welcome to the first global edition of The Column. This issue sees a merger with The Peak from LC–GC North America to create one global digital magazine.

Utilizing the ultra-high efficiency provided by core-shell technology columns, thirteen pain management opioids were resolved in 1.5 minutes with one second wide peaks at base on a Kinetex C18 2.6 ?m 50 x 2.1 mm column.

The Merck Young Scientist award will return for a third year to honour Malaysian post-graduate students in the fields of bioscience and chromatography.

A modification of the popular PLE technique is discussed.

Can you qualify or calibrate your chromatograph using a system suitability test? No. However, for the doubters out there this column will explain why.

LCGC and Spectroscopy review some of the highlights and award recipients from this year's ASMS conference, held May 23–27, 2010, in Salt Lake City, Utah.

A discussion on the analytical challenges that both liquid chromatography and mass spectrometry face as well as some potential solutions to these issues.

Many volatile organic compounds (VOCs) found in a variety of consumer products are potentially harmful to human health and the environment. Within industry, to regulate product safety and quality, methods for measuring specific VOCs in a product, typically by thermal desorption gas chromatography–mass spectrometry (TD-GC–MS), are implemented. Such analysis provides a comprehensive VOC profile. However, the nature of some products, such as food, can be chemically complex. Within this complexity, trace-level or coeluting compounds can be difficult or time-consuming to identify. As a potential solution, new software tools are being developed to automate interpretation of the data.

The authors explain some of the primary differences between quadrupole and time-of-flight mass analyzers and provide information regarding the benefits of each in their use for gas chromatography applications.

Waters and the University of Maryland are establishing an international training laboratory to teach scientists from foreign governments and manufacturers the state-of-the-art analytical methods used to meet US food safety standards.

With May's ASMS Conference now receding in the collective rearview mirror of the industry, the summer is as good a time as any to take stock of the analytical chemistry marketplace. This year's show, held in Salt Lake City, Utah, demonstrated once again the vitality and robustness of the field of mass spectrometry, as innovation and technological advancement were in evidence everywhere you looked.

The increasing use of pesticide testing coupled with reductions in maximum permissible residue levels of pesticides in food have driven demand for fast, sensitive, and cost-effective analytical methods for high-throughput screening of multiclass pesticides in food. Detection of 510 pesticides at low parts-per-billion levels can be achieved within minutes using orbital trap technology. The high resolving power of these systems enables accurate mass confirmation of all compounds, including isobaric pesticides. This article will provide an overview of current legislation and illustrate how mass spectrometry instrumentation can enable fast and accurate pesticide screening.

Fast turnaround time is critical in the clinical testing environment. Here, fast liquid chromatography (LC) technologies were utilized for the comprehensive assay of commonly prescribed pain management drugs in under 2 min. The use of fast LC also provided significantly improved sensitivity. A mini-validation for these analytes in human urine was performed and acceptable values for accuracy, precision, linearity, lot-to-lot variability, and matrix effects were demonstrated for each analyte.

It is estimated that up to 4.5 trillion cigarette butts are stubbed, flicked and dropped every year. With few practical uses, any attempt at recycling the remains has been difficult; however a study published in Industrial & Engineering Chemistry Research proposes using them to prevent steel corrosion and could turn this trash into a tiny treasure.

Dionex has received a pair of awards, the Frost & Sullivan 2010 Best Practices Award for Global Process Chromatograph New Product Innovation, and the NorthFace Scoreboard Award from the Omega Management Group in recognition of world class customer service.

Peas, beans and some other plant seeds contain proteins, called globulins, which have been shown to act as a defence against insects and other herbivores. Coffee beans contain large amounts of globulins, so scientists in Brazil studied the beans to assess their potential for warding off insects.

A study performed by researchers from the Madrid Institute for Advanced Studies and the University of Almeria, Spain, has revealed the presence of 88 pollutants in the river waters of Madrid. The research, published in the Journal of Environmental Analytical Chemistry, found that while compounds are to a great extent eliminated at wastewater treatment plants, a fraction remains in the river water.
