    摘要： A capillary mixing device, comprising a liquid impervious housing; an interior space in the housing comprising a chamber in the housing having capillary spacing in one dimension and non-capillary spacing in other dimensions; and a plurality of magnetic or magnetically inducible particles in the chamber. The chamber is normally accessed through one or more capillary passageways leading to a surface of the housing and is adapted to be retained by a magnetic device that comprises means for generating a moving magnetic field and means for retaining the chamber device in an orientation so that the magnetic field has a field vector that intersects the capillary chamber perpendicular to the dimension having capillary spacing.

    摘要： Provided herein are systems and methods for detecting a compromised flow line in a laboratory instrument. In one embodiment, for example, the system includes: (1) a wash station in fluid communication with a sample probe; (2) a fluid line coupled to the wash station to withdraw fluid from the wash station and deliver the fluid to a waste tank; and (3) a vacuum transducer, coupled to the fluid line, to measure vacuum pressure per unit time within the fluid line. The vacuum pressure per unit time is then used to detect a compromised flow line (e.g., a clog, occlusion, opening, etc. in the flow line).

    摘要： A diagnosis system, which comprises a monitor, comprising a detector providing multiple reflectance readings in an array of individual locations, registering an analytical cartridge in the monitor at a fixed location and orientation relative to the array, and determines and displays analytical results from reflectance readings; and an analytical cartridge, comprising a liquid impervious housing, a sample application site in the housing located outside the monitor when the cartridge is registered in the monitor by the means for registering, one or more reflectance reading sites in the housing that register with one or more of the locations in the array, a capillary pathway in the housing leading from the sample application site to each of the reflectance reading sites, and a reflectance matrix located in at least one of the reflectance reading sites. In some embodiments of the invention, control features that optimize accuracy of measurement by controlling when and if sample reaches reflectance reading sites and by drawing excess sample away from undesirable locations in the cartridge are present. One control element balances the liquid-holding capacities of the application site, the sample-transporting capillary passageway that leads to the reflectance reading site, and the porous matrices from which the reflectance reading will be made, so that excess sample is excluded from entry into the cartridge while sample volumes that are below the minimum necessary for accurate operation do not reach the matrix, thereby avoiding false readings.
