| 20100258784 | Method Of Efficient Coupling Of Light From Single-Photon Emitter To Guided Radiation Localized To Sub-Wavelength Dimensions On Conducting Nanowires - A cavity free, broadband approach for engineering photon emitter interactions via sub-wavelength confinement of optical fields near metallic nanostructures. When a single CdSe quantum dot (QD) is optically excited in close proximity to a silver nanowire (NW), emission from the QD couples directly to guided surface plasmons in the NW, causing the wire's ends to light up. Nonclassical photon correlations between the emission from the QD and the ends of the NW demonstrate that the latter stems from the generation of single, quantized plasmons. Results from a large number of devices show that the efficient coupling is accompanied by more than 2.5-fold enhancement of the QD spontaneous emission, in a good agreement with theoretical predictions. | 10-14-2010 |

An extended ion funnel is located in the vacuum system of the mass analyzer and has an ion focusing section and an ion mobility analyzing section. The carrier gas together with entrained ions is introduced into the ion focusing section where the ions are focused to the axis of the funnel by applied RF voltages. In the ion mobility section, the action of an RF quadrupolar field, the movement of the carrier gas and axial DC field, separates the ions on the basis of their mobilities. The mobility separated ions are released into the mass analyzer where the ions may be further separated on the basis of mass. | 05-26-2011 |
| 20110139976 | Method for operating three-dimensional RF ion traps with high ion capture efficiency - In a three-dimensional Paul RF ion trap the ring electrode and end cap electrodes are formed from pairs of pole rods.

| 20120273670 | Spectrum Acquisition Modes For Ion Mobility Spectrometers Using Trapped Ions - In an ion mobility spectrometer in which a gas flows through a gas-tight tube with a radially quadrupolar RF field therein and blows ions against a DC electric field barrier, a mobility scan with a mobility scale that is linear in time is obtained by holding the height of the DC electric field barrier constant while changing the pressure and temperature conditions of the flowing gas. Alternatively, the mobility scan is performed by holding the pressure and temperature conditions of the flowing gas constant and reducing the height of the DC electric field barrier non-linearly with respect to time. | 11-01-2012 |
| 20120273673 | Selective Ion Mobility Spectrometer - Ions with a predetermined range of ion mobilities are produced by filtering input ions with at least two consecutive ion mobility high pass and/or low pass filters. Each ion mobility filter is formed by entraining ions in a moving gas and applying a DC electric field to the ions which causes the ions to move in a direction opposite to the gas flow. An ion mobility high pass filter is formed when the DC electric field drives the ions against the flow of gas, whereas an ion mobility low pass filter is formed when a the gas flow drives entrained ions against an DC electric field barrier. | 11-01-2012 |
| 20120273674 | Resolution Enhancement For Ion Mobility Spectrometers - In an ion mobility spectrometer in which a gas pushes ions along a spectrometer axis against and over an electrical field barrier, the electric field barrier is generated with a plateau of slightly increasing height along the axis of the spectrometer. Alternately, the electric filed barrier may have a plateau with constant height, but the gas flow decreases in velocity along the axis of the spectrometer in the vicinity of the plateau. | 11-01-2012 |
| 20120286156 | SELECTIVE ION MOBILITY SPECTROMETER - Ions with a predetermined ion mobility range are produced by filtering ions entrained in a stream of moving gas with two ion mobility low pass filters located consecutively in the gas stream. Each filter is formed by applying a DC electric field to the gas stream which causes the ions to move in a direction opposite to the gas flow. Ions are collected between the two filters and transferred to a detector or analyzing device. In one embodiment, the maximum field strength of the electric field barrier in the first ion mobility low pass filter is continued as a plateau of essentially constant field strength up to the electric field barrier in the second ion mobility low pass filter, which has a maximum field strength higher that the maximum field strength of the electric field barrier in the first ion mobility low pass filter. | 11-15-2012 |
| 20120298860 | MEANS AND METHOD FOR FIELD ASYMMETRIC ION MOBILITY SPECTROMETRY COMBINED WITH MASS SPECTROMETRY - Analyte ions are analyzed first by field asymmetric ion mobility spectrometry (FAIMS) before being analyzed by a mass analyzer. Analyte ions are produced at near atmospheric pressure and transferred via a dielectric capillary into the vacuum system of the mass analyzer. While passing through the capillary, the ions are analyzed by FAIMS via electrodes on the interior wall of the capillary. Improved ion transmission is achieved by providing smooth geometric transitions between the channel in FAIMS analyzer and the channel in the remainder of the capillary. | 11-29-2012 |

| 20130009051 | ABRIDGED ION TRAP - TIME OF FLIGHT MASS SPECTROMETER - An improved trap-TOF mass spectrometer has a set of electrodes arranged to produce both a quadrupolar RF confining field and a substantially homogeneous dipole field. In operation, ions are first confined by the RF field and then, at a selected time, the RF confining field is discontinued and the dipole field is used to accelerate the ions so as to initiate a TOF MS analysis. The apparatus of the present invention may be used alone or in conjunction with other analyzers to produce mass spectra from analyte ions. | 01-10-2013 |
