    摘要: The present disclosure is related to improved systems and methods for delivering samples for high-throughput mass spectrometric analysis to an atmospheric-pressure ionization source. In an exemplary embodiment, the system includes a solvent reservoir for storing a solvent solution, a first valve which is coupled to the solvent reservoir, first and second pumps for delivering solvent solution and which are coupled to the first valve and which the delivery flow rate of the first pump is greater than the delivery flow rate of the second pump, an injection system having a sample injector and an second valve which is coupled to the first valve and which is capable of being coupled to can be couple to an electrospray ionization source. In another embodiment, the system can also include an atmospheric-pressure ionization chamber, an atmospheric-pressure ionization sprayer and a nebulizer gas source and a voltage supply source. In yet another embodiment, the system may further include a puffer valve that is coupled to the nebulizer gas source and the atmospheric-pressure ionization sprayer and a gas puffer that is coupled to the puffer valve. A distal end of the gas puffer may be located within the atmospheric-pressure ionization chamber and aligned with the distal end of the atmospheric-pressure ionization sprayer and the puffer valve may control the delivery of the nebulizer gas to the atmospheric-pressure ionization sprayer and the gas puffer.

    摘要: Sample processing units useful for mixing and purifying materials, such as fluidic materials are provided. A sample processing unit typically includes a container configured to contain a sample comprising magnetically responsive particles, and one or more magnets that are in substantially fixed positions relative to the container. A sample processing unit also generally includes a conveyance mechanism configured to convey the container to and from a position that is within magnetic communication with the magnet, e.g., such that magnetically responsive particles with captured analytes can be retained within the container when other materials are added to and/or removed from the container. Further, a sample processing unit also typically includes a rotational mechanism that is configured to rotate the container, e.g., to effect mixing of sample materials disposed within the container. Related carrier mechanisms, sample processing stations, systems, and methods are also provided.
