Whatman SPE固相萃取柱

固相萃取柱有8种反向试剂也运用Florisil、二氧化硅和离子交换样品浓缩柱可选用多种吸附剂重量/体积具有样品纯化的滤膜配套与大多数真空复式接头配套Whatman固相提取柱用于HPLC、GC、TLC或其它技术分析的样品的制备。其特点是外壳为聚丙烯材料，内部可选用各种硅基填料，硅基填为有8种可选择的反相化学试剂，普遍用于农药滤渣的FlorisilTM填料，二氧化硅和离子交换。样品干燥装置含无水硫酸钠。与Whatman PartisilTM HPL填料一样，所有包装都是高质量的。为进一步的纯化样品，有些固相提取柱配有0.2μm聚丙烯滤膜，这种滤膜与大多数有机溶剂配套，且过滤后*溶出物。Whatman固相提取柱有两种类型，一为容500mg吸附剂的柱子与Luer Lok针筒配套使用；另为有各种重量/体积比的吸附剂可供选用的柱体。柱体与大多数多歧式接头的真空固相萃取仪或自动化系统配套使用，也可单独使用。样品浓缩柱该柱呈圆筒形，可直接与Lure Lok注射器相连接。用注射器推动，使样品经过浓缩柱，收集于小瓶，并去除水分。该柱含无水硫酸钠，能结合样品中的水分，形成NA2SO4＊10G2O,若需再干燥，可将二个或多个柱连接起来使用。 Whatman SPE devices have silica-based chemistries and are available in several configurations. Column capacities include 3, 6 and 12 mL sizes. A cartridge format is also available for use with a syringe .
