Abstract
Embodiments of the invention relate to a clinical instrument analyzer system for the automatic analysis of patient samples. In one embodiment, the analyzer may be used to analyze bodily fluid samples, such as blood, plasma, serum, urine or cerebrospinal fluid, for example. Embodiments of the invention relate to an apparatus and method, for example, an immunoassay method, for separating out target molecules in a magnetic field and then analyzing those target molecules with a luminometer.
Claims16
A system for manipulating magnetic particles in a vial comprising:
- a vial;
- a receiving member with an inlet sized and shaped to fit said vial and position said vial in a magnetic washing station, said magnetic washing station comprising a magnet array configured for generating said magnetic field, said magnet array comprising a stack of three magnets comprising,
- a first magnet comprising an upper horizontal surface and a vertical surface, wherein a north pole face of said first magnet is positioned adjacent to and facing said vial and a south pole face of said magnet is facing away from the vial,
- a spacer comprising an upper horizontal surface, wherein said spacer is positioned on said upper horizontal surface of said first magnet,
- a second magnet comprising an upper horizontal surface and a vertical surface, said second magnet positioned on said upper horizontal surface of said spacer, wherein a north pole face of said second magnet is positioned adjacent to and facing said vial and a south pole face of said second magnet is facing away from the vial, and
- a third magnet comprising an upper horizontal surface and a vertical surface, said third magnet positioned on said upper horizontal surface of said second magnet, wherein a south pole face of said third magnet is positioned adjacent to and facing said vial and the north pole face of said third magnet is facing away from the vial.
A system for manipulating magnetic particles in a vial comprising:
- a vial;
- a receiving member with an inlet sized and shaped for holding a said vial containing magnetic particles;
- and
- a magnet array configured to generate a magnetic field in the vial, the magnetic array comprising,
- a first magnet comprising an upper horizontal surface and a vertical surface, wherein a south pole face of said first magnet is positioned adjacent to and facing said vial,
- a spacer comprising an upper horizontal surface, wherein said spacer is positioned on said upper horizontal surface of said first magnet,
- a second magnet comprising an upper horizontal surface and a vertical surface, said second magnet positioned on said upper horizontal surface of said spacer, wherein a south pole face of said second magnet is positioned adjacent to and facing said vial, and
- a third magnet comprising an upper horizontal surface and a vertical surface, said third magnet positioned on said upper horizontal surface of said second magnet, wherein a north pole face of said third magnet is positioned adjacent to and facing said vial.
