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: 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: The present invention describes a method and apparatus for separating chemical and/or biological samples based on selective ion-molecular interactions in the gas phase. A chemical modifier is added to the drift gas that interacts selectively with a targeted molecule in at least one component of the sample in a drift tube. The component may be impurities and/or interferences in the sample whereby the chemical modifier enhances sample resolution by shifting the components drift times. In addition, reagents can be added to the sample prior to, during, or after ionization to form a complex with selected components in the sample. In addition, one or more internal and/or external standard can also be added to the sample as a calibration for the measurement.

摘要: The present invention describes separating components in a sample in an ion mobility based spectrometer using at least one matching property of the components other than the molecular properties in conventional ion mobility measurements in noble drift gases to enhance separation and resolution of the sample. Separation based on the matching property is realized by altering the drift media of the IMS. Besides altering drift media, energy level of ions and/or drift media are also controlled during the separation process. This invention describes an ion mobility apparatus wherein an energy source is added to the IMS that provides additional energy to the ions and/or drift media and tuning methods that involve selecting drift media and optimizing the energy level in order to achieve optimal performance.
