Zusammenfassung:	A vial cap (54) for removing a matrix component from a liquid sample is described. The vial cap (54) includes a cap body (202), an inlet portion (204), and an outlet portion (206). The cap body (202) is configured to have a slidable gas and liquid seal with a side wall of a sample vial (44). The inlet portion includes a counterbore section (210) that holds a filter plug (42). The filter plug (42) includes a polyethylene resin and a material selected from the group consisting of an ion exchange material and a reversed-phase material. The vial cap is adapted for solid phase extraction for use in an autosampler with a plurality of sample vials.
