Abstract: An apparatus for processing a laboratory sample contained in a laboratory sample container is presented. The apparatus comprises an optical sensing unit for sensing a transmittance at different vertical positions through the laboratory sample container and a tip sensing unit having a tip. The tip sensing unit is adapted to provide a tip sensing signal (tLDS) depending on a position of the tip relative to the sample. The apparatus also comprises a process control unit adapted to control the secure and reliable pipetting of the laboratory sample in response to both the transmittance and the tip sensing signal (tLDS) provided by the tip sensing unit.

Abstract: An electrochemiluminescence method of detecting an analyte in a liquid sample and a corresponding analysis system. An analyte in a liquid sample is detected by first providing a receptacle containing a fluid comprising protein coated magnetic microparticles to a stirring unit. Stirring of the fluid is necessary since the density of the microparticles is usually higher than the density of the buffer fluid. Thus the microparticles tend to deposit on the bottom of the receptacle leading to an aggregation of the microparticles because of weak interactions. To obtain representative measurements a homogeneous distribution of the microparticles in the buffer fluid is necessary to ensure a constant concentration of microparticles for each analysis cycle. It is further necessary to provide disaggregation of the microparticles, which is also realized by stirring the fluid. Stirring is conducted with a rotational frequency that is adapted to the amount of fluid to be stirred.

Abstract translation: 用于检测液体样品中的分析物的电化学发光法和相应的分析系统。 通过首先将含有包含蛋白质包被的磁性微粒的流体的容器提供到搅拌单元来检测液体样品中的分析物。 流体的搅拌是必需的，因为微粒的密度通常高于缓冲液的密度。 因此，由于弱相互作用，微粒倾向于沉积在容器的底部，导致微粒的聚集。 为了获得代表性的测量，需要在缓冲液中均匀分布微粒以确保每个分析循环的微粒的恒定浓度。 还需要提供微粒的解聚，这也是通过搅拌流体来实现的。 以适合于待搅拌的流体的量的转动频率进行搅拌。
