采用 Thermo Scientific™ Dionex™ AutoTrace™ 280 自动固相萃取(SPE)系统从大体积水性基质分析痕量有机物。该自动系统可捕获和浓缩待测分析物,所以一次运行可在 2-3 小时内处理 6 个样品,操作时间仅 15 分钟。典型应用包括 PAH、PCB、PCDD、PCDF、农药、除草剂、阻燃剂、半挥发性物质、亚硝胺和类固醇。
该系统可实现达 6 种样品的自动 SPE——来自萃取柱或萃取盘调节、样品加载、冲洗和洗脱步骤、清洗和洗脱。
Dionex SolEx SPE 萃取柱有多种化学键合相和尺寸可供选择,可捕获和浓缩大体积水性基质中的待测分析物。
配件包括试剂瓶、试管、支架以及与 Dionex Auto Trace 280 配用的维修工具包。
Dionex AutoTrace 280 自动固相萃取仪非常适合寻求自动化大体积水萃取的实验室。典型应用包括 PAH、PCB、PCDD、PCDF、农药、除草剂、阻燃剂、半挥发性物质、亚硝胺和类固醇。Dionex AutoTrace 系统应用含多个美国 EPA 方法和各种其它 SPE 样品制备净化方法,包括:
