Abstract: A method of determining an analyte concentration in a sample by a sensor is disclosed. The method includes analyzing a sample signal generated by the sensor for an analyte being measured. If the sample signal is normal, the method includes comparing the sample signal with a first reference signal of a reference solution measured prior to measuring the sample in order to determine the analyte concentration. If the sample signal is abnormal, the method includes comparing the sample signal with a calculated reference signal point obtained by interpolation between the first reference signal and a second reference signal of the same reference solution measured after measuring the sample. Various methods of determining and handling errors based on signal patterns are also disclosed.
Abstract: A loading device for loading a reagent rotor of an analytical instrument with reagent vessels is disclosed. The loading device comprises a tray to receive reagent vessels.

The loading device also comprises a transporting device for transporting the reagent vessels from the tray to the reagent rotor of the analytical instrument. The tray is formed such that the transporting device is linearly moveable within a second plane from the unloading position of the tray to the reagent rotor and/or from the reagent rotor to the unloading position of the tray. The first plane and the second plane are different from one another. The tray is formed as a circular ring segment.

Abstract: A method of operating an analytical laboratory is presented. The method comprises recording time at which samples are first identified; retrieving an order list comprising test orders for the samples; retrieving a degradation limit to each test order; determining workflows for each sample; instructing the laboratory instruments to carry out the test orders according to the workflows. Determining the workflows comprises i) determining target instruments capable of carrying out the test orders; ii) determining a sequence/timing of the test orders; iii) calculating an estimated completion time for each test order; iv) determining a lead time for each sample and test order; v) prioritizing test orders if the lead time exceeds the degradation limit. Steps ii) to v) are repeated until the lead time doesn't exceed the degradation limit for any of the test orders; or until steps ii) to v) have been repeated for a number N of iterations.

Abstract: A method of operating a laboratory sample distribution system is presented. The system comprises container carriers, a transport plane, and drive elements. The container carriers carry sample containers. The transport plane supports the container carriers. The drive elements move the container carriers on the transport plane. The method comprises planning a movement path for a container carrier from a start to a goal on the transport plane modelled by nodes. The nodes are free for one time-window or reserved for one-time window. The planning comprises analyzing the reachability out of a free time-window of one node to free time-windows of a next node and an over-next node such that planned movement of the container carrier is nonstop. The method comprises reserving the planned movement path comprising a sequence of time-windows of nodes and moving the container carrier along the reserved movement path on the transport plane by a drive element.
