Styre Screen® extraction columns contain an ultra clean, highly cross-linked styrene and divinylbenzene copolymeric sorbent. The sorbent can be functionalized with ,any of the same phases as our silica based sorbents. Possibilities include standard hydrophilic, hydrophobic, or ion exchange functionalities as well as our co-polymeric phases such as the DBX or THC phases. SPE materials based on a polymeric sorbent have increased analyte capacity versus silica based materials. This means that less sorbent bed mass is needed. The result is faster flow rates and less solvent use. Higher throughput and less solvent waste disposal translate into significant savings in both time and money. In addition, no conditioning steps are required for most drugs of abuse applications.
