Abstract
A flow control assembly for use in preparation of samples for analysis by solid phase extraction includes a housing assembly having a first passage communicating with a needle bore and locating a solid phase sorbent, a second fluid port, and a valve for selective aspiration or delivery of fluid across a solid phase sorbent, or bypassing the solid phase sorbent. Independent flow paths are provided for a sample via the needle, and of the elution solvent via a separate port. The valve includes relatively slideable first and second members, the second member including an elongate shank that is relatively reciprocably slideable for effecting selective aspiration or delivery of fluid between first and second relative positions. A third fluid port may be provided communicating with the elongate second passage for selective fluid communication with a port in a shank when the shank is at the second relative position.
