    摘要: An apparatus for multiple nano-spray delivery of a sample to FAIMS analyzer includes a micro-machined ionization source having a plurality of discrete nozzles. At least some of the discrete nozzles of the plurality are aligned one each with an ion inlet of a plurality of discrete ion inlets of the FAIMS, so that ions produced at different discrete nozzles are introduced into different portions of the FAIMS analyzer region. The ions that are introduced via each ion inlet are at least partly separated prior to adding/mixing with the ions introduced via other ion inlets. This reduces the problems of ion-ion electric repulsions that occur when ion density is high.

    摘要: A method of separating ions, including a first species of ion and a second species of ion that are transmitted through an analyzer region under substantially identical electrical field conditions, is provided. The method includes separating ions within an analyzer region according to the FAIMS principle, such that the first species of ion and the second species of ion are selectively transmitted along a time-averaged first direction through a portion of the analyzer region between the ion origin end and the ion detection end. Subsequently, the first species of ion and the second species of ion within the analyzer region are separated according to a difference in low field ion mobility values, such that relatively more of one of the first species of ion and the second species of ion is transmitted to an ion detection end than is transmitted absent separating the first species of ion and the second species of ion within the analyzer region according to a difference in their low field ion mobility values. The ions are transmitted through the remainder of the analyzer region under normal FAIMS operating conditions.

    摘要: A high field asymmetric waveform ion mobility spectrometer (FAIMS) for separating ions, and a method therefore. The FAIMS includes an electrode stack (24) having a length and comprising a plurality of electrodes (26, 28). Each electrode of the electrode stack is spaced apart from an adjacent electrode in a direction along the length of the electrode stack, and each electrode of the electrode stack has an edge that defines a portion of an edge of the electrode stack. At least an electrode (22) is spaced apart from the edge of the electrode stack in a direction approximately transverse to the length of the electrode stack, the space between the at least an electrode and the edge of the electrode stack defines an analytical gap (20) for allowing ions to propagate therebetween. Ions are separated as they move through an electric field within the analytical gap resulting from the application of an asymmetric waveform voltage to alternate electrodes of the electrode stack and application of a direct current voltage to at least some of the electrodes of the electrode stack and to the at least an electrode.
