摘要： A LED backlight module including a diffusion plate, at least an optical devices, at least a light-emitting diode and a second reflection surface is provided. The optical device is provided underneath the diffusion plate and has a first reflection surface. The light-emitting diode is provided underneath the optical device, for emitting light to the first reflection surface where first reflection of the light is performed. The second reflection surface is provided underneath the light-emitting diode, for receiving the light of the first reflection and performing second reflection of the received light. By controlling light paths of LED with the optical devices, light emitted from LED may be leaded to a specific direction instead of directly emitting from a front surface of LED, so as to achieve the performance of color-mixing and uniform distribution.

摘要： The present invention relates to a preconcentrator for vapors and particles collected from air. The vapor preconcentrator is made from plural layer of coils. The coil is made of resistance alloy. The pitch size of the coil is made to precisely trap/filter out certain size of the particles during preconcentration. Multiple coils could be made with different pitch sizes to achieve multiple step filtrations. When the sample flow enters the preconcentrator chamber, it passes through the coils. The particles of different sizes are trapped on different layer of coils. The vapor sample can be trapped on any coils when interacted with the coil surface. They could be trapped without any affinitive coating as the preconcentrator is at relatively low temperature. Different coils or different sections of the coil can be coated with different material to trap chemicals of different classes. During the desorption process, the coils are flash heated with controlled temperature ramping speed to evaporate the trapped chemicals. Various configurations, constructions, and methods of operation are presented.

摘要： The present invention relates to improving the ability of a hyphenated instrument to analyze a sample benefiting from having the first instrument's analysis of the same sample. A fast switching mechanism can be used as the interface between an ion mobility spectrometer (IMS) and a mass spectrometer (MS) such that the obtained IMS spectrum is converted into a timing diagram that controls the vacuum inlet's size dynamically during analysis of a neutral and/or charged chemical and/or biological species such that a smaller pumping system can be used.

摘要： The IMS apparatus and methods described in this invention involve setting the ion detector at the highest potential of the drift tube and setting the ionization source at ground or near ground potential. The methods allow significantly simple sample introduction without the limitation of the high potential (voltage) concern of the front end sample delivery. The invention also describes bringing samples directly into the ion mobility drift tube. The invention further describes using single syringe for sample introduction via an electrospray ionization method.

摘要： A second gate in an Ion Mobility Spectrometer is used to select or block different time windows of the ion mobility spectrum. A second gate in the Ion Mobility Mass Spectrometer is used to modulate peak intensities in the IMS spectrum, allowing each peak in the IMS spectrum to be unambiguously matched with its set of fragment ions in a subsequent MS-MS mass spectrum.

摘要： An ion mobility spectrometry method wherein ions are separated along a drift axis while providing a drift gas flow in a direction that is substantially neither in the direction of the drift axis nor opposite to the drift axis. Ion mobility spectrometer operation methods use a cross-directional gas flow in a drift tube and/or a segmented drift tube for pre-separation.

摘要： One aspect of the present invention is to extract multiple ionic species in a FAIMS into one or more IMS drift tubes simultaneously. By adjusting FAIMS operational parameters, ions in FAIMS are detected on IMS detectors through separation in FAIMS and/or separation and collection in the IMS. This method provides a continuous separation of specific ions from an ion swarm by employing a high-field differential mobility analyzer (FAIMS) with a plurality of orthogonal transitions paths spaced incrementally along the electrodes which allow additional separation by a conventional IMS drift tube. The components of the sample can be collected or detected.
