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Florisil
TM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NA2SO
4*10G2O,若需再干燥,可將二個或多個柱連接起來使用。
