摘要:
The methods described herein generally relate to characterization of large analytes, such as biomolecules, by molecular mass analysis. Specifically, the methods are directed to molecular mass analysis of singly— or multiply-charged ions by selective ion filtering carried out by a digital thresholding process.

The present invention provides devices, apparatuses, and systems for lifting and mounting of clinical- and research-related equipment. In particular, the present invention provides a lift and mount system for mass spectrometers (e.g., for time of flight (TOF) mass spectrometers (MS)).
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.

The present invention provides a method for rapid solution capture purification of nucleic acids for subsequent analysis by electrospray mass spectrometry which is efficient and cost-effective relative to existing methods. The present invention also provides kits useful for practicing rapid solution capture of nucleic acids so that purified samples are in condition for analysis by electrospray mass spectrometry.

摘要:
The present disclosure is related to improved systems and methods for inducing infrared multiphoton dissociation (IRMPD) of an ion. In an exemplary embodiment, the system includes an ion dissociation chamber and an infrared waveguide coupled to the ion dissociation chamber. The infrared waveguide may be positioned to receive infrared energy from an infrared energy source and direct the infrared energy towards ions in the ion dissociation chamber for the purpose of fragmenting the ions. The infrared waveguide can be made of a hollow fused silica body with an inner infrared reflective layer. The infrared waveguide may be flexible. A system may further include a focusing lens, an infrared transparent window and an aperture housing that has an orifice. The ion dissociation chamber may be an ion trap, an ion guide or an ion reservoir. In one embodiment, ions may be directed into an ion storage area of an ion dissociation chamber, the infrared energy is directed into the infrared waveguide which is aligned with the ion storage area and then infrared energy is delivering to the ions located within the ion storage area.
