24 Claims

1. A device for use in processing a volume of fluid that contains suspended solids and solubles, comprising: a structure receivable by an autosampler and integrating a first inlet chamber in fluid communication with a first outlet chamber through an integral fluid pathway, each chamber accessible at a top opening by one or more autosampler needle(s); and a separation medium disposed in the first inlet chamber such that a fluid injected by the one or more autosampler needle(s) into the first inlet chamber traverse the separation medium prior to transport through the pathway to the first outlet chamber, wherein gravitational flow of fluids between the first inlet chamber and first outlet chamber is prevented by at least one blocking element.
