Abstract: The present disclosure relates to a method and a solid phase microextraction sampling instrument for inserting into or through a solid or semisolid material to extract a component of interest from a sample, comprising a support structure at least partially coated with an extraction phase for extracting the component of interest, a protrusion that shields the coating during insertion, where the distances within a cross-sectional plane of the sampling instrument are greater than or equal to the corresponding distances in all of the cross-sectional planes located between the cross-sectional plane of interest and the insertion end of the sampling instrument. The present disclosure also discusses methods of making the instrument, desorption chambers, and methods for desorbing a component of interest from the instrument.

Abstract: The invention describes the process by which a standard mixture of organic compounds are spiked and retained onto a composite sorbent matrix for the controlled generation of a standard in fluid above the spiked matrix either in a gaseous or aqueous phase. The novelty of the aforementioned composite matrix stems from the combination of an immobilizing liquid phase such as silicone oil or a polyacrylonitrile solution, and solid, porous particles such as polystyrene-co-divinylbenzene (PS-DVB) or hydrophilic/Lipophilic Balance (HLB) particles to strongly retain the spiked standards. These novel composite mixtures exhibit sorptive capabilities greater than the sum of their individual components. In addition swelling of the particles with the liquid phase facilitates immobilization of the composite sorbent matrix in the vial.

Abstract: The invention describes the process by which a standard mixture of organic compounds are spiked and retained onto a composite sorbent matrix for the controlled generation of a standard in fluid above the spiked matrix either in gas (headspace) or aqueous phase which is contained in portable vials. The novelty of the aforementioned composite matrix stems from the combination of an immobilizing liquid phase such as silicone oil or a polyacrylonitrile solution, and solid, porous particles such as polystyrene-co-divinylbenzene (PS-DVB) or Hydrophilic/Lipophilic Balance (HLB) particles to strongly retain the spiked standards facilitating high capacity which translates into prolonged use as a source of calibrant. These novel composite mixtures exhibit sorptive capabilities greater than the sum of their individual components producing a standard analyte generator far superior to those described in the prior art.

Abstract: Various entities need to share data among team members working on the same project without investing in specialized server software. To address this need, an existing standard file server is used to host data for sharing among the team. The file server has not been customized to share the data for the particular application. A user creates a special folder for a project at a user specified location on the file server. Data associated with the project is converted to files and stored in a structure of folders used by the file server to represent the data that is shared. Each client that has subscribed to this shared data synchronizes the data on their local computing device with the data on the file server. Security is provided by using the file server's built-in access controls.

Abstract: Described is a system and method that enables project management across application programs, including an email program, calendar program, spreadsheet program, word processing program, note taking program and others. A central project-related view provides access to project-related data items and may display a schedule, a task list of tasks filtered as being relevant to a project, a note page related to a project, and emails relevant to the project. In addition, other application objects (file, documents, presentations and spreadsheets) are also captured in the view and presented for easy access. Metadata including a project identifier is maintained in a database for the various data items, allowing rapid location of the data items related to a project via query techniques. A project palette allows access to the items from within another application program, and a project gallery allows a user alternative access to the files related to a project.
