Whatman SPE固相萃取柱
固相萃取柱有8種反向試劑也運用Florisil、二氧化硅和離子交換樣品濃縮柱可選用多種吸附劑重量/體積具有樣品純化的濾膜配套與大多數真空復式接頭配套Whatman固相提取柱用于HPLC、GC、TLC或其它技術分析的樣品的制備。其特點是外殼為聚丙烯材料，內部可選用各種硅基填料，硅基填為有8種可選擇的反相化學試劑，普遍用于農藥濾渣的FlorisilTM填料，二氧化硅和離子交換。樣品干燥裝置含無水硫酸鈉。與Whatman PartisilTM HPL填料一樣，所有包裝都是高質量的。為進一步的純化樣品，有些固相提取柱配有0.2μm聚丙烯濾膜，這種濾膜與大多數有機溶劑配套，且過濾后*溶出物。Whatman固相提取柱有兩種類型，一為容500mg吸附劑的柱子與Luer Lok針筒配套使用；另為有各種重量/體積比的吸附劑可供選用的柱體。柱體與大多數多歧式接頭的真空固相萃取儀或自動化系統配套使用，也可單獨使用。樣品濃縮柱該柱呈圓筒形，可直接與Lure Lok注射器相連接。用注射器推動，使樣品經過濃縮柱，收集于小瓶，并去除水分。該柱含無水硫酸鈉，能結合樣品中的水分，形成NA2SO4＊10G2O,若需再干燥，可將二個或多個柱連接起來使用。 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 .
