Title: Apparatus and method for mobility separation of ions utilizing an ion guide with an axial field and counterflow of gas
Inventor: LOBODA ALEXANDRE V
IPC: G01N27/64
Filed: 2003-04-24
Abstract: Method and apparatus to control movement of ions in a mass spectrometer, an ion guide has means for generating an electric field along the ion guide, and also provision for generating a counterflow gas in the opposite direction of the electric field along the ion guide. This then subjects ions to forces, an electric field force and a drag force. These can be set to control motion of ions as desired. The ion guide can form part of ion mobility section, in which case the forces can be set to enhance separation of ions and to control elution of different groups of ions from the ion mobility spectrometer for subsequent analysis. Eluted ions can be selected to further analysis, e.g., collisional fragmentation followed by mass analysis in a time-of-flight instrument. The technique is applicable to other elements of a mass spectrometer; for example, the fragmentation cell can be configured so that ions therein are subjected to both drag forces and electric forces, to control movement thereof.

Title: Composite closure having an insert with a peripheral curl
Inventor: GERMAN GALEN
IPC: B65D41/34
Filed: 2004-08-11
Abstract: A composite closure (10) for a standard 40 mm opening is configured to form a cavity (40) to house a curl (52) of the insert disc.
