operating principles of the direct-electron ionization (EI) interface, which is becoming more popular in many LC–MS applications. Matrix effects and the role of direct-EI as a universal detector for small molecule analysis are also discussed in detail. The advantages and drawbacks of this approach are described and a comparison with atmospheric pressure ionization (API) interfaces is made. The potential of direct-EI is illustrated with a selection of practical applications. 2011-01-01T05:00:00Z http://www.chromatographyonline.com/lcgc/data/articlestandard/lcgc/062011/706366null XML http://www.chromatographyonline.com/lcgc/GC/Hydrogen-Carrier-Gas-amp-Vacuum-Compensation/ArticleStandard/Article/detail/709613?contextCategoryId=42402&ref=25 A look at the effect of choosing hydrogen carrier gas on column selection and when using direct-interface GC–MS 2011-01-01T05:00:00Z http://www.chromatographyonline.com/lcgc/data/articlestandard/lcgc/102011/709613/GCconnectthumb_thumbnail.jpg http://www.chromatographyonline.com/lcgc/data/articlestandard/lcgc/102011/709613/GCconnectflash_flash.jpg XML http://www.chromatographyonline.com/lcgc/GC/Determining-Phthalates-using-GCndashAPCI-ToF-MS/ArticleStandard/Article/detail/709617?contextCategoryId=42402&ref=25 A novel and sensitive approach for analysing high-molecular-weight phthalates is described. 2011-01-01T05:00:00Z http://www.chromatographyonline.com/lcgc/data/articlestandard/lcgc/102011/709617/sandrathumb_thumbnail.jpg http://www.chromatographyonline.com/lcgc/data/articlestandard/lcgc/102011/709617/sandraflash_flash.jpg XML http://www.chromatographyonline.com/lcgc/Column%3A+Validation+Viewpoint/Method-Validation-Back-to-Basics-II/ArticleStandard/Article/detail/706361?contextCategoryId=42402&ref=25 The authors discuss the specifics of analytical method validation. 2011-01-01T05:00:00Z http://www.chromatographyonline.com/lcgc/data/articlestandard/lcgc/062011/706361/ValView_T_thumbnail.jpg http://www.chromatographyonline.com/lcgc/data/articlestandard/lcgc/062011/706361/ValView_F_flash.jpg XML http://www.chromatographyonline.com/lcgc/News/Poisonous-dwarf-frogs/ArticleStandard/Article/detail/704818?contextCategoryId=42402&ref=25 There are four types of poisonous frogs known to secrete lipid?soluble alkaloids derived from their food.
