The technique uses simple glassware, a minimal amount of organic solvent and various salt/buffer additives to partition analytes into an organic phase for clean up by dispersive solid-phase extraction (d-SPE). The technique provides good recoveries, is reproducible and costs less than other sample preparation approaches. The technique is being adopted by many laboratories worldwide. It has the potential for applications outside of the pesticide in foods area. 2008-02-01T05:00:00Z http://www.lcgcasia.com/lcgcasia/data/articlestandard/lcgcasia/062008/490102null XML http://www.lcgcasia.com/lcgcasia/GC+Connections/A-Split-Decision/ArticleStandard/Article/detail/490101?ref=25 This instalment of "GC Connections" discusses factors that can help determine which type of liquid injection technique is appropriate for specific samples, including having to use existing inlet systems that are on-hand in the laboratory with samples for which they might not be ideally suited. 2008-02-01T05:00:00Z http://www.lcgcasia.com/lcgcasia/data/articlestandard/lcgcasia/062008/490101null XML http://www.lcgcasia.com/lcgcasia/Application+Note/Simultaneous-Determination-of-Nicotine-and-Metabol/ArticleStandard/Article/detail/490212?ref=25 2008-02-01T05:00:00Z http://www.lcgcasia.com/lcgcasia/data/articlestandard/lcgcasia/062008/490212null XML http://www.lcgcasia.com/lcgcasia/Application+Note/Analysis-of-Nonionic-Ethoxylated-Surfactants-Using/ArticleStandard/Article/detail/490106?ref=25 Nonionic ethoxylated surfactants (e.g., alkylphenol ethoxylates and fatty alcohol ethoxylates) are widely used in industrial and consumer products.
