The SmartPrep Cartridge Extractor II for method development and automation of previously developed manual methods is a second-generation system with additional features and improved ruggedness. Positive pressure consistently delivers the sample and solvents, yielding reproducible unattended results. Cartridges of 1, 3 and 6-mL size from most manufacturers can be used in the system, easing the transition to automation. More extensive reporting and the implementation of an optional bar code reader speed the auxiliary tasks required when performing sample preparation. The instrument is designed for special environmental applications, such as 1,4 dioxane, nitrosamines, acetamide herbicide degradates, food preparation such as aflatoxins in peanut paste, and energy methods such as furans in transformer oils.
