Head-space solid-phase microextraction (SPME) was used to isolate/extract volatile compounds followed by GC–TOF-MS to identify tainted compound in contaminated soft drinks. Direct analysis in real time–time-of-flight mass spectrometry (DART–TOF-MS) was also used to obtain negative and positive ion profiles of different soft drinks to determine the presence of various compounds, including antimicrobial preservatives, artificial sweeteners, acidulants and saccharides, without any sample preparation and chromatographic separation. 2008-05-01T04:00:00Z http://www.lcgceurope.com/lcgceurope/data/articlestandard/lcgceurope/182008/513718null XML http://www.lcgceurope.com/lcgceurope/Column+Watch/Column-Pressure-Considerations-in-Analytical-HPLC/ArticleStandard/Article/detail/513721?ref=25 In this instalment of "Column Watch", columnist Ron Majors examines the role of pressure in high performance liquid chromatography (HPLC) from two viewpoints: the impact of the ultrahigh pressures encountered in ultrahigh-pressure liquid chromatography (UHPLC) on chromatographic parameters and increases in column pressure encountered in normal daily use. The latter is of more practical consequence to HPLC users because increased back pressure usually implies that something has gone wrong with the column. Pressure increases as a result of physical and chemical contamination are explored and practical approaches to solve these problems are suggested. 2008-05-01T04:00:00Z http://www.lcgceurope.com/lcgceurope/data/articlestandard/lcgceurope/182008/513721null XML http://www.lcgceurope.com/lcgceurope/Practical+Data+Handling/Assessment-of-Accuracy-in-Chromatographic-Analysis/ArticleStandard/Article/detail/513720?ref=25 The assessment of accuracy, which involves the estimation of precision and the determination of trueness, refers to the process of evaluating whether the results provided by analytical methods are close to accepted reference values.

The empirically observed and modelled behaviour of grafted long alkyl chain adlayers on a silica surface were in good agreement. The empirical data was also compared with data using analogous systems and these also matched well. This approach has the potential to gain much greater insight into the behaviour of reversed-phase (RP) columns and could help to design column surfaces that are resistant to phase collapse. 2008-02-01T05:00:00Z http://www.lcgceurope.com/lcgceurope/data/articlestandard/lcgceurope/062008/490140null XML http://www.lcgceurope.com/lcgceurope/Glossary-of-HPLCLC-Separation-Terms/ArticleStandard/Article/detail/513204?ref=25 In 2001, the second glossary of common and not-so-common terms and "buzz words" for reference to HPLC columns and column technology was published. It is time for an update since new terms have arisen or, in some cases, their original meanings have expanded or changed. 2008-02-01T05:00:00Z http://www.lcgceurope.com/lcgceurope/data/articlestandard/lcgceurope/182008/513204/Column-Watch---thumb_thumbnail.jpg http://www.lcgceurope.com/lcgceurope/data/articlestandard/lcgceurope/182008/513204/Column-Watch---main_main.jpg http://www.lcgceurope.com/lcgceurope/data/articlestandard/lcgceurope/182008/513204null XML http://www.lcgceurope.com/lcgceurope/LC+Troubleshooting/The-Perfect-Method-Part-6-Make-It-Faster/ArticleStandard/Article/detail/490130?ref=25 Trade extra resolution for speed. 2008-02-01T05:00:00Z http://www.lcgceurope.com/lcgceurope/data/articlestandard/lcgceurope/062008/490130null XML http://www.lcgceurope.com/lcgceurope/NEW-LIQUID-CHROMATOGRAPHY-COLUMNS-FROM-VARIAN-INC-/ArticleStandard/Article/detail/487201?ref=25 NEW LIQUID CHROMATOGRAPHY COLUMNS FROM VARIAN, INC.
