Oasis在线样品前处理柱使复杂样品基质(如血浆或血清)中某一特定分析物或代谢物的全在线分析成为可能。无需离线样品前处理，将样品稀释后即可进样。提供三种不同的Oasis在线样品前处理柱：
A. Oasis卡套柱：可装入SentryTM 柱套中使用，手拧即可方便而快速地进行更换
B. Oasis直接连接色谱柱：可直接拧接到切换阀上，或与类似常规HPLC色谱柱的接头相连
C. Oasis色谱柱：具有与传统HPLC色谱柱一样的接头和硬件
将Oasis在线样品前处理柱与沃特世窄内径分析色谱柱(如XSelect、XBridge、SunFire、Atlantis、XTerra、或Syetry)配合使用，可以实现对复杂样品基质中的特定分析物的快速在线分析。五种Oasis吸附剂(HLB、MCX、MAX、WCX、WAX)的不同粒径规格均已配齐，方便选择。
带有在线SPE技术的UPLC系统整合了自动的样品处理装置，专业的色谱媒介，高灵敏度的光学检以及质谱检测器，形成了在线的SPE/LC/MS/MS解决方案。配合以下三种UPLC可耐压的在线SPE小柱，即可萃取待分析物。
