摘要: The invention relates to a substance determining apparatus (19) for determining a substance within a fluid. A location event determination unit (34) determines location events indicating that a particle, which may have attached the substance, is located in a sensing region and a property of the location events from the sensing signal generated by sensing the sensing region. A location events selection unit (70) selects a part of the location events having a property in a predefined property range, and a substance determination unit (40) determines the substance within the fluid (3) based on the selected part of the location events. This allows tuning the determination of the substance within the fluid to a desired property range, which can relate to a desired kind of bound particles, thereby reducing the influence of unwanted effects on the determination of the substance and, thus, improving the determination accuracy.

摘要: The invention relates to a cartridge(10) and its use in an examination apparatus(100). A sample(1) can be introduced into an inlet(11) of the cartridge(10) and conducted through a channel(12) to a reaction chamber(13). In the reaction chamber(13), an examination of the sample takes place, for example by frustrated total internal reflection. An agent(21) is applied to the sample close to the inlet(11), wherein said agent(21) is preferably stored in a reservoir(16) at the inlet(11). In this way the filling time of the reaction chamber(13) is simultaneously used for the incubation of the sample with the agent(21). Moreover, the filling-course of the cartridge and/or the reaction chamber may preferably be determined and taken into account during the execution of the examination and/or the evaluation of the results.

摘要: A system and method wherein components of a reagent such as labeled antibodies are separated from a biologically active sensor surface by depositing the reagent on a carrier surface distinct from a sensor surface in a detection region. The present device provides a short, well-defined and controlled, pre-incubation time between the particles of interest in the sample fluid and the reagent, thereby increasing the reproducibility by providing all components in one detection region such as a detection chamber.

摘要: A system and method is described wherein components of the reagent (4), e.g. labelled antibodies, are separated from the biologically active sensor surface (5) by depositing the reagent (4) on a carrier surface (3) distinct from the sensor surface (5) in the detection region (2), e.g. detection chamber. In this way, a high assay reproducibility is obtained. By allowing a short, well-defined and controlled, pre-incubation time between the particles of interest, e.g. drugs, in the sample fluid (20) and the reagent (4), the reproducibility will be increased, whereas the speed of the assay is guaranteed by having all components in one detection region (2), e.g. detection chamber.
