Solid Phase Extraction (SPE) Columns

Dispersive SPE (dSPE), often referred to as the "QuEChERS" method (Quick, Easy, Cheap, Effective, Rugged, and Safe), is modern sample prep technique that is becoming increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products. Using the QuEChERS method,...

Oasis HLB sample extraction products contain a polymeric water-wettable reversed-phase sorbent. When combined with a simple, generic methodology, HLB sorbent allows the extraction of a wide range of compounds in various matrices with high reproducible recoveries.

Empore membrane SPE technology comprises of SPE particles tightly enmeshed within a network of inert PTFE fibrils (90% SPE particles : 10% PTFE, by weight). The SPE-membrane fabrication process results in a highly dense and uniform extraction medium that offers distinct advantages over traditional...
