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: There is provided an automatic analyzer that can reduce a cleaning agent used for cleaning a puddle configured to stir a reagent including a fine particle. An automatic analyzer including a reagent container configured to accommodate a reagent including a fine particle, a puddle configured to stir the reagent, and a cleaning unit configured to immerse the puddle in a cleaning vessel reserving a cleaning agent. The automatic analyzer further includes a determining unit configured to determine whether to totally replace the cleaning agent based on a score computed using a number of times of cleaning the puddle having stirred the reagent in the cleaning unit and a remaining amount of the reagent. When the determining unit determines that the cleaning agent is totally replaced, the cleaning unit displays, on a screen, a notification of total replacement of the cleaning agent, or recommendation of the total replacement.

Abstract: An installation switch has an insulating housing and a terminal connecting arrangement for clamping a connecting conductor having an annular terminal shoe. The terminal connecting arrangement includes a terminal socket having an interior disposed between an insertion opening for receiving the terminal shoe and an access opening and a terminal screw having a screw head and a screw shank disposed in the interior of the terminal socket, the screw being actuatable in a longitudinal direction within the interior of the terminal socket between an open state and a clamped state. The arrangement further includes a connection plate having a screw hole with interior threads for threadably engaging the terminal screw when in the clamped state and a retaining device preventing the terminal screw from being removed from the terminal socket when in the open state.

Abstract: An installation switch having a housing and a connecting arrangement for a conductor having a terminal shoe. The connecting arrangement includes a socket having an interior, an insertion opening, and an access opening, and a screw having a screw head and a screw shank disposed in the interior of the socket. The screw is actuatable longitudinally between an open and a clamped state. The arrangement further includes a connection plate having a screw hole with threads for threadably engaging the screw when in the clamped state, and a retaining device preventing the screw from being removed when in the open state. The arrangement is configured so that the open state allows the shoe to be inserted into the insertion opening, the clamped state provides the screw being engaged with the shoe, and access to the screw is provided via the access opening of the socket to actuate the screw.
