    摘要: In a process for titrating substances by adding increments of a titrant in time intervals, the course of the reaction is monitored in its approach toward the end point (EP), and the addition of titrant is controlled. At least one differential component is determined from the course of the reaction and used for controlling the addition of titrant. The process can be performed by an apparatus that includes a delivery unit for the titrant and suitable devices for performing the monitoring, differentiating and control functions.

    摘要: An analyzer system has a base housing (1) and a sample tray (4) with at least two holding accommodations (5) for containers (32) of samples that are to be analyzed. The sample tray (4) is movably supported on the base housing. A drive mechanism (2) inside the base housing advances the tray (4) so that the containers (32) move in steps along a prescribed track to an analyzer module (16), where the samples are subjected to an analysis. A lid-opening device (50) is arranged along the prescribed track at a place that the sample containers (32) reach before they arrive at the analyzer module (16). The lid-opening device (50) serves to open lids (32′) of a predetermined shape and thickness (H) by which the sample containers (32) may be covered. The lids (32′) are preferably made of a non-magnetic material containing a magnet-anchor element.
