PerkinElmer has reported its financial results for the fourth quarter of 2008. Revenue from continuing operations was $495.0 million, an increase of 3% versus the fourth quarter 2007.

Many businesses have recently adopted the federal government guidelines for drug testing of employees. It is common for initial testing to be performed by test strips for fast screening. Positive results are then confirmed by GC-MS. The goal of this application is to show the anticipated chromatographic responses expected when similar conditions are applied to Zebron columns.

Velocity11 renamed

Agilent Technologies has renamed Velocity11 as Agilent Automation Solutions. Agilent acquired Velocity11 in late 2007 and continues its focus on automating laboratory processes by introducing the Direct Drive Robot and VWorks Automation Control Software.

A team of scientists from Agricultural Research Service (ARS) and Abraxis, Inc. compared the a new triclosan test, called "magnetic particle enzyme immunoassay," to the more traditional method-gas chromatography-mass spectrometry (GC-MS). They hope that this test, which detects triclosan at a concentration of 20 parts per trillion (ppt)-the equivalent of 1 ounce in 31 million tons, can expedite environmental monitoring of this widely used antibacterial agent in rivers, wells, and other bodies of water.

A research group from the Mendel University of Agriculture and Forestry (Brno, Czech Republic) and the Academy of Sciences of the Czech Republic (Trebon, Czech Republic) combined solid-phase exraction (SPE) and supercritical fluid extraction (SFE) using an SPE cartridge incorporated in an SFE cell to extract benzoic acid and cinnamic acid derivatives from microalgae and cyanobacteria samples.

Researchers from the Chinese Academy of Sciences (Beijing, China) developed a method for analyzing human thrombin using affinity probe capillary electrophoresis (CE) with laser-induced fluorescence (LIF) detection.

Researchers from Germany, Belgium, the UK, and Australia conducted a study of urine from patients with and without coronary artery disease to look for proteome patterns indicative of the disease.

The current acetonitrile shortage is an important factor in pushing analysts in the pharmaceutical, food, environmental, and chemical industries toward considering the use of ultrahigh?pressure liquid chromatography (UHPLC) as a means to save solvent.

Filtration Conference

The American Filtration and Separations Society will be holding its 22nd Annual Technical Conference and Exhibition on May 4-7, 2009, at the Sheraton Hotel in Bloomington, Minnesota.

SEC Analysis of Xanthan

Xanthans are high molecular weight polymers that have the ability to raise the viscosity of water dramatically. This is exploited in oil recovery processes, where xanthan acts as a water thickener.

Researchers from the Chinese Academy of Sciences (Beijing, China) and the University of Science and Technology of China (Hefei, China) used a two- and three-phase hollow-fiber liquid-phase microextraction method to determine aromatic amines in environmental water samples.

Researchers from Universita ?La Sapienza? (Rome, Italy) used a matrix solid-phase dispersion technique with hot water as the extracting solvent to extract seven quinolone antibacterial agents from egg samples.

Researchers from the Bio-Molecular Innovation Team of LGC (UK) used polymerase chain reaction (PCR) and Agilent?s DNA 1000 chip and model 2100 capillary electrophoresis (CE) system to analyze raspberry and strawberry DNA.

Many businesses have recently adopted the federal government guidelines for drug testing of employees created by NIDA (The National Institute on Drug Abuse) and SAMSHA (The Substance Abuse and Mental Health Services Administration) as a result of federal legislation or drug related accidents and deteriorating work performance.

Waters Corporation (Milford, Massachusetts) has acquired Thar Instruments (Pittsburgh, Pennsylvania), a supercritical fluid chromatography (SFC) manufacturer.

Researchers from Queen's University (Kingston, Ontario, Canada) developed porous polymer capillary columns with varied flurous content for chromatography of tagged analytes.

There are a host of volatile organic compounds (VOC) in sea salt that originate from several sources such as the surrounding plants, algae, bacteria and environmental pollution. A team of scientists from the University of Aveiro, one region where sea salt is produced, reasoned that the combination of VOC from the different local sources could be sufficient to create a unique fingerprint of the salt.
