摘要：

The use of solid-phase extraction disks as a sample clean-up device is described. The disks contain a membrane composed of resin beads permanently enmeshed in a polytetrafluoroethylene membrane, housed in a medical-grade polypropylene housing. The resin within the membrane is functionalized to retain specific types of components from the sample. Several chemistries are developed to remove various interfering components. The recovery of the ions after sample treatment is examined.
