  • Publication number: 20090282932
    Abstract: A device and method for extending the useful life of a bulk liquid used in an automated clinical analyzer. Air from the atmosphere surrounding the automated clinical analyzer that displaces the bulk liquid consumed from a container is routed through a gas scrubber in order to remove or at least reduce the quantity of at least one contaminant present in that air. The gas scrubber is positioned between the bulk liquid in the container and the atmosphere surrounding the container. The gas scrubber contains a reagent that is capable of reacting with a contaminant in the atmosphere, whereby a required characteristic(s) of the bulk liquid does (do) not change excessively prior to the date that the bulk liquid is consumed. For example, if the contaminant is carbon dioxide, and the required characteristic of the bulk liquid is the level of pH of the bulk liquid, the reagent in the gas scrubber prevents the level of pH of the bulk liquid from changing excessively prior to the date that the bulk liquid is consumed.

  • Publication number: 20090117620
    Abstract: A laboratory automation system that is capable of carrying out clinical chemistry assays, immunoassays, amplification of nucleic acid assays, and any combination of the foregoing, said laboratory automation system employing at least one of micro-well plates and deep multi-well plates as reaction vessels. The use of micro-well plates as reaction vessels enables the laboratory automation system to assume a variety of arrangements, i.e., the laboratory automation system can comprise a variety of functional modules that can be arranged in various ways. In order to effectively carry out immunoassays by means of micro-well plates, a technique known as inverse magnetic particle processing can be used to transfer the product(s) of immunoassays from one micro-well of a micro-well plate to another.

  • Publication number: 20080024301
    Abstract: A system for automation of laboratory analyzers that utilizes radio frequency identification (RFID) tags and radio frequency identification (RFID) readers to identify containers and vessels, and the contents thereof, that are employed in the system. Radio frequency identification tags, conforming to the guidelines of ISO 14443 or ISO 15693 or ISO 18000, are positioned on the items of interest, such as, for example, reagent containers, sample containers, and microplates. These tags can be read by and written to by either a moving antenna of a RFID reader or a stationary antenna of a RFID reader. Reading of RFID tags and writing to RFID tags are controlled by software.

  • Patent number: 6562298
    Abstract: The embodiments disclosed relate to determination of an item of interest in a sample. One embodiment relates to a structure which comprises a process path. The process path comprises a process lane including a process step performance lane where a process step is performed, and a process step avoidance lane where the process step is avoided. A first prime mover is operatively connected with the process path for moving a container holding the sample along the process path. A first pipetting system is operatively associated with the process path for introducing the sample to the container. A second pipetting system is operatively associated with the process path for introducing a reagent to the container. A device is operatively connected with the process path and is selectively engagable with the container for mixing the sample and the reagent in the container.

  • Patent number: 6022746
    Abstract: Methods of allocating resources in a system comprising at least two instruments are provided. In one such method, a list of tests to be performed by the system within a reaction vessel is generated. The list includes a number of reaction vessels used in performing each test to be performed by the system in a given time period. The list of tests is sorted according to the number of reaction vessels used in performing each test to be performed by the system in a given time period. A duplication percentage for the tests is determined. The duplication percentage is compared with the sorted list of tests. Resources associated with the tests are duplicated across the at least two instruments based on the comparison of the duplication percentage with the sorted list of tests such that at least one of the tests is performed by at least two of the at least two instruments.

    Abstract: The embodiments disclosed relate to determination of an item of interest in a sample. In one method, a process path comprising a process lane including a process step performance lane where a process step is performed, and a process step avoidance lane where the process step is avoided is provided. A container holding the sample is moved along the process path. The sample is introduced to the container. A reagent is introduced to the container. The sample and the reagent are mixed in the container. The container is selectively positioned in a selected one of the process step performance lane and the process step avoidance lane. The item of interest in the sample is determined based upon a reaction between the sample and the reagent.

  • Patent number: 5795784
    Abstract: Embodiments described herein provide methods of performing a process for determining an item of interest in a sample. In one embodiment, a container for holding the sample is accepted in a process lane where a process step is selectively automatically performed on the sample in the container. The process step is selectively automatically performed on the sample in the container. An effective length of the process lane is maintained constant while a physical length of the process lane is selectively varied.
