    • The invention relates to a flow through system for quantifying a target component in a liquid. The flow through system comprises a flow-through device comprising a flow path comprising a marker section, a capture section downstream to said marker section, and at least two quantification sections. The marker section comprises a non-immobilized marker. The capture section comprises a capture zone with an immobilized capture agent, and the at least two quantification sections comprise a pre-capture quantification section placed downstream to the marker section and up stream to the capture section, and a post-capture quantification section placed downstream to the capture section. The system further comprises a quantification unit for each of said quantification sections. The quantification unit(s) being arranged to quantify marker containing components and/or particles passing through said respective quantification sections. The invention also relates to a flow through device for such flow through system and a method of determining the amount of target component in a liquid using a flow through system.

    • The invention relates to a microfluidic device comprising a flow path with a first and a second opposite solid flow path surfaces (1) and a liquid inlet for said flow path. In the microfluid device at least one solid side wall free section (2) of the flow path (1) is provided by the first and the second opposite solid flow path surfaces in at least said one solid side wall free section (2) and a pair of borderlines (3, 31) defines the edges of the side wall free section (2) of said flow path (1). The pair of borderlines is placed on the first surface of a first and a second opposite surfaces to define the flow path surfaces of said first and second opposite surfaces. The pair of borderlines (3, 31) is defined by an abrupt change of the first and/or the second surface, e.g. in the form of an abrupt change of surface tension and/or an abrupt change of distance between the first and second surfaces beyond and adjacent to the borderlines (3, 31). For example the borderlines (3, 31) may be arranged with a sharp edge with an angle between a flow path surface in the side wall free flow path section and the respective surfaces beyond and, adjacent to the borderlines which is less than 135 degrees, such as about 90 degrees. The flow path comprises an immobilized capture reagent (7) downstream from or in said solid side wall free flow path section (2), said immobilized capture reagent (7) preferably being immobilized onto at least one of said first and second opposite solid flow path surfaces.
