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.

The session titled ?Separations at the Edge: High Temperature, Pressure and Speed II? is a continuation of Tuesday?s Part I session and will be chaired by Gert Desmet of Vrije Universiteit Brussel (Brussels, Belguim) and Uwe Neue of Waters Corporation (Milford, Massachusetts) in Ballroom B.

Terry Berger of Berger Instruments (Newark, Delaware) and Geoffrey Cox of Chiral Technologies, Inc. (West Chester, Pennsylvania) will chair a Monday morning session titled "Chiral Separations" in Ballroom B.

A Wednesday morning session titled "Surface Properties, Interactions and Retention Selectivity" will be held in Ballroom B starting at 10:30 a.m. The Session Chairs will be Georges Guiochon of the University of Tennessee (Knoxville, Tennessee) and Wolfgang Lindner of the University of Vienna (Vienna, Austria).

Agilent Technologies has been selected by the South African Doping Control Laboratory as the primary provider of gas-phase testing instruments for the 2010 World Cup. The South Africa Doping Laboratory is equipped with state-of-the-art gas chromatography and mass spectrometry instruments from the company, which will be used to confirm the chemical identity of suspected banned substances found in testing samples.

The session titled "Pharmaceutical Analysis" will be chaired by Wolfgang Goetzinger of Amgen Inc. (Cambridge, Massachusetts) and Robert Plumb of Imperial College (London, UK) on Tuesday afternoon in Ballroom A.

We have reached Day 3, the final day of LCGC's coverage from HPLC 2010, and somehow, it never fails to surprise us to find that we've concluded another week of coverage. However, HPLC still has plenty to offer, including another full day of technical sessions and exhibits tomorrow, so we hope you can take advantage of everything the conference has to offer in your remaining time.

The Monday morning plenary lectures will be held in Ballroom ABC beginning at 8:30 a.m., and the Session Chair will be Barry Karger of the Barnett Institute at Northeastern University (Boston, Massachusetts).

Good morning, and welcome to LCGC's first day of show coverage from HPLC 2010, held this year in Boston, Massachusetts, at the Hynes Convention Center.

Monday morning's session titled Monoliths I, to be held in Ballroom B, will be chaired by Karin Cabrera of Merck KGa (Darmstadt, Germany) and Emily Hilder of the University of Tasmania (Hobart, Australia).

Good Morning and welcome to Day 2 of LCGC's continuing coverage of HPLC 2010. We hope you've been able to take in some of the sights and sounds of Boston, Massachusetts, in addition to attending the many technical sessions and exhibitor booths at this year's conference.

The new HT800L from HTA is a fast and versatile HPLC autosampler for highly precise injections into HPLC, UHPLC and LC/MS systems.

Squalene and squalane are oils, often used in the production of cosmetics and vaccines. Originally derived from the liver oil of deepwater sharks, squalane is also available from olives, and since 2008 some important cosmetic firms have claimed to switch to this more ethical squalane supply. However, the shark oil offers a higher yield and lower costs, so suppliers face the temptation to disguise the oil?s origin, while continuing to exploit sharks. A method in Rapid Communications in Mass Spectrometry is reported to reveal the source, protecting sharks, as well as cosmetic firms and consumers.

Chiral Technologies is partnering with Vanderbilt University?s programme in drug discovery to supply enantioselective chiral chromatography columns and custom separation services.

In the forests of Borneo in South-East Asia, a carnivorous pitcher plant, Nepenthes rafflesiana, lures, traps and digests small animals, mainly insects. As part of the lure, the pitchers copy flowers in a variety of ways, producing nectar as well as using bright colours and ultraviolet patterns. A study published in the Journal of Ecology has shown that this mimicry also includes a range of floral scents to trick insects to their demise.
