The Montreal Gazette published an article about the use of analytical techniques in the wine industry. The author discusses the difference between "natural" wines and "industrial" wines that are created with a certain taste profile in mind and with the assistance of gas chromatography.
AC Analytical Controls developed a new chromatographic solution that complies with all ASTM & EN chromatographic test methods listed in biodiesel specifications: the AC all-in-one Biodiesel analyser. Analysis results demonstrate that the AC analyser complies with EN 14103, EN 14105, EN 14106, EN 14110 & ASTM D6584 methods.
Different methods require different strategies.
Cleaning validation is a major analytical application in the pharmaceutical industry. Here, high performance liquid chromatography (HPLC) with charged aerosol detection is compared and contrasted to HPLC with UV detection showing comparable performance and several advantages for charged aerosol detection, especially for analytes that do not contain a chromophore.
In the fourth installment in a series on method development for liquid chromatography (LC), with an emphasis on devloping trouble-free methods quickly. John Dolan started out by considering some of the goals we might have and some method development strategies.
Columnist Ron Majors covers some of the highlights of HPLC 2007 including honorary sessions, best poster awards, and the latest developments in HPLC column technology.
Liquid chromatography (LC) separations performed at elevated temperatures offer the following advantages.

Waters is acquiring Calorimetry Sciences, a manufacturer of high-performance calorimeters.
In an article recently published in Public Health Nutrition that discusses medicinal herbs? growing popularity, researchers report that While Western medicine currently employs pure, single compounds, CM has long used multiple combinations of compounds in the form of processed natural products, primarily medicinal herbs, to treat and relieve the symptoms of many different human diseases.
In an article recently published in Analytica Chimica Acta, researchers describe the simultaneous determination of sulfamonomethoxine, sulfadimethoxine, and their N4-acetyl metabolites in eggs using restricted-access media high performance liquid chromatography (RAM-HPLC) with a photo-diode array detector.
In an article recently published in the Journal of Nutrition, researchers reported that a mixture of anthocyanins from bilberries and blackcurrants reduced levels of transcription factor NF-kB - responsible for orchestrating a wide range of inflammatory responses.
In an article recently published in Analytica Chimica Acta, researchers developed a procedure for the determination of artemisinin in A. annua using high performance liquid chromatography (HPLC) with evaporative light scattering detection (ELSD) in couple with microwave-assisted extraction (MAE) as an efficient sample preparation technique. Afterwards, method validation system for HPLC?ELSD analysis was developed.
In an article published in Microchemical Journal, researchers used HPLC to determine the linuron preconcentrated on octadecyl silanized (ODS) magnetite.
In this installment of "Column Watch" columnist Ron Majors revisits expert predictions from a survey conducted in 1987. A cross section of column experts of the time were asked a series of questions on the future directions in high performance liquid chromatography (HPLC) column technology. Now, 20 years later, these predictions are contrasted against current column technology. In many cases, the experts were entirely correct, while in other cases, they were dead wrong. Some current trends were not even considered 20 years ago. The author backs up his analysis with current survey information.
