摘要:
The invention relates to an analysis system for analysing an analyte contained in a sample of body fluid. Said system comprises a test element (3) that respectively comprises a housing (15) and an analysis function channel (16) that is surrounded by the housing (15), and an evaluation device (2) comprising a measuring station (6) for measuring a measurement variable characterising the analysis result in the measurement zone (19) of the test element (3), and comprising a preferably rotatable maintaining element for maintaining a test element (3). Said test element (3) comprises an air flow channel (25) having two wider sections (26a, b) and a narrow section (27) that is arranged between said wider sections (26a, b). Said wider sections (26a, b) have a cross-sectional surface that increases compared to the narrow section (27) in the direction away from said narrow section, and a connection channel (24) is arranged in such a manner between the narrow section (27) and the analysis function channel (16) that an air exchange connection is formed, the air flow channel (25) being arranged in such a manner that low pressure produced by means of an air flow flowing through the air flow channel (25) acts upon the analysis function channel (16).
摘要:
Method and system for carrying out heterogeneous chemical or biological reactions, the method comprising the steps of providing an analytical device comprising at least one liquid processing unit, the liquid processing unit comprising at least one reaction chamber, and at least a first inlet channel in fluid communication with the reaction chamber, supplying to the reaction chamber via the first inlet channel or a second inlet channel analyte capturing particles, supplying to the reaction chamber via the first inlet channel or the second inlet channel a liquid sample containing at least an analyte of interest, confining by an equilibrium of forces the analyte capturing particles in a particle rearrangement zone comprised in the reaction chamber, said forces comprising a drag force Fd generated by liquids flowing through the first inlet channel and a counter-oriented force Fg, capturing analytcs present in the liquid sample with the particles in the particle rearrangement zone.
