摘要： A method of trapping ions using a quadrupole ion trap device includes applying quadrupole excitation to trapped precursor ions causing them to be driven into the ring electrode where they undergo surface induced dissociation. The resultant product ions are then trapped within the ion trap device.

摘要： A quadrupole ion trap device has a field adjusting electrode located outside the trapping region adjacent the aperture in the entrance end cap electrode, and optionally adjacent the aperture in the exit end cap electrode. The field adjusting electrode(s) controls field distortion in the vicinity of the apertures. By appropriately setting the voltages on the field adjusting electrodes the efficiency and resolution of operational processes such as ion introduction, precursor ion isolation and mass scanning can be improved.

摘要： A method, apparatus, media and signals for generating a computer representation of a three-dimensional swept envelope of a vehicle having a wheeled chassis operable to support a vehicle body for movement along a terrain is disclosed. The method involves receiving terrain data representing a 3D terrain, receiving data defining parameters of the vehicle, and receiving data defining a path for movement of the vehicle from an initial position on the terrain to a displaced position on the terrain. The method also involves disposing a computer representation of the vehicle on the 3D representation of the terrain at successive locations along the path using the parameters. Disposing involves determining points of engagement between wheels of the wheeled chassis and the 3D representation of the terrain to dispose the chassis with respect to the terrain, and determining a corresponding 3D location of the vehicle body with respect to the terrain. The method further involves generating a plurality of spatial extents of the vehicle at the successive locations, the spatial extents defining the 3D swept envelope of the vehicle when moving between the initial position and the displaced position. In another aspect a method for generating a computer representation of a three-dimensional swept envelope of an object moving along a guideway disposed with respect to a 3D representation of a terrain is disclosed.

摘要： The current invention involves a method and a device for generating and analyzing ions in order to analyze samples directly without sample preparation. The gaseous neutral molecules are desorbed under atmospheric pressure by a desorption method. The desorbed neutral molecules are then transferred into a low pressure region where they are post-ionized by a mist from an electrospray probe tip or by photons from a vacuum UV source. The generated ions are then focused in a time varying electric field in the low pressure chamber before they are transferred into a mass spectrometer or ion mobility spectrometer for further analysis.

摘要： Gel particles or beads can be prepared by forming a hot aqueous solution of a gelling agent, and discharging the hot gelling agent solution through a discharge orifice into a cold moving stream of hydrophobic liquid so that the gelling agent solution cools rapidly and good quality gel particles coalesce in the cold hydrophobic liquid stream. The cold hydrophobic liquid stream can be contained in a conduit so that the cold hydrophobic liquid stream moves past the discharge orifice and exerts a force on hot solution in the discharge orifice, the force acting to withdraw the hot solution from the discharge orifice. Optionally, the gel particles can be crushable gel beads 10 formed of an agar complex providing cosmetic, pharmaceutical, etc. delivery vehicles for topical delivery of biologically or cosmetically active agents. Preferred agar beads 10 are complexes of a continuous phase of agar gel 12 in a self-supporting solid or semi-solid form with a restraining polymer 14. Various active agents 16 may be bound to restraining polymer 14, for, example ascorbic acid, lactic acid or papain.
