Faster Analysis of Naproxen Tablets — Improvements on the USP Method
July 2nd 2010The costs associated with pharmaceutical testing are considerable, and many lab managers are seeking ways to reduce costs by reducing solvent usage and improving productivity while still using the LC instruments in their lab.
The Use of Novel Software for the Identification of Trace Compounds in Complex Mixtures
July 1st 2010Many 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.
Comparing the Capabilities of Time-of-Flight and Quadrupole Mass Spectrometers
July 1st 2010The 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.
Taking Stock of the Mass Spectrometry Marketplace
July 1st 2010With 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.
Rapid analysis of polycyclic aromatic hydrocarbons
June 25th 2010A rapid gradient HPLC method for simultaneous determination of 16 PAH according to EPA 610 method is presented. A baseline resolution for all 16 target analytes in less than 2.50 minutes could be achieved by using a KNAUER BlueOrchid PAH 50 x 2 mm column.
