A method using a chemical analyzer for removing a component of a liquid sample which may interfere with a test performed on a test assay includes the steps of adding the liquid sample to a sample cup, transferring a volume of the liquid sample to a mixing cup containing an IMAC (Immobilized Metal Affinity Chromatography) resin containing porous beads to form a sample/resin solution in the mixing cup, using a pipette of the chemical analyzer to repeatedly aspirate the sample/resin solution into a disposable pipette tip of the pipette and expelling the sample/resin solution from the pipette tip into the mixing cup to achieve a mixed sample/resin solution in the mixing cup, and allowing the mixed sample/resin solution in the mixing cup to rest undisturbed so that the interfering component of the liquid sample adheres to the porous beads and the beads settle to a bottom portion of the mixing cup, resulting in a refined liquid sample devoid of the interfering component and occupying an upper portion of the mixing cup for later dispensing on the test assay.

The present invention provides a system and method for a surface plasmon resonance measuring and injection system and to a method for surface plasmon resonance measurement using the so-called cuvette-injection-flow system.

An automatic analyzer for making measurements for different analysis processes by a compact mechanism. The apparatus performs inspection for plural different analysis processes and includes: an incubator for holding plural reaction vessels on circumferential positions, first and second dispensing mechanisms each having a dispensing nozzle capable of arc-shaped movement around a rotational axis and vertical movement, in which a first locus of an arc-shaped movement of the dispensing nozzle of the first dispensing mechanism and a second locus of the arc-shaped movement of the dispensing nozzle of the second dispensing mechanism intersect the circumference of the incubator where the reaction vessels are arranged, while the first locus and the second locus do not intersect, the first dispensing mechanism is used in a first inspection having a first reaction period, and the second dispensing mechanism is used in a second inspection having a second reaction period longer than the first reaction period.

An all-in-one machine for sample testing and a corresponding control method thereof are disclosed. The all-in-one machine is divided into an upper portion driven by an upper driving unit and a lower portion driven by a lower driving unit. Through the coordinated movement of the upper driving unit and the lower driving unit, the movement process can achieve both high speed and high precision, thus improving the testing efficiency and accuracy. The lower driving unit can achieve a larger range of movement adjustment to meet various extreme distance requirements. Corresponding uncapping/capping mechanisms are designed for sample tubes, extraction kits, and amplification kits to achieve automated uncapping/capping operations. The effective connection of disposable medical consumables is ensured through a process operation monitoring module. By designing separate air ducts, the internal interference of the equipment is minimized and the risk of contamination is reduced.
