whatman spe固相萃取柱上海摩速公司代理的详细介绍
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florisil
tm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,且过滤后绝无溶出物。
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na2so
4*10g2o,若需再干燥,可将二个或多个柱连接起来使用。
