摘要： A laser is used in the detection of explosives residue by creating micro-detonations of explosive particles adhered to objects. An object is scanned with a beam of coherent laser light to induce micro-detonations of micro-particles of explosive residue adhered to the object. Temporal and spectral information representative of light emitted by the micro-particles is used to characterize the explosives.

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： 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： An apparatus for separating ions includes providing a FAIMS analyzer region defined by a space between a first electrode surface and a second electrode surface and extending between an ion inlet end and an ion outlet end. An asymmetric waveform is applied to the first electrode surface and a compensation voltage difference is applied between the first and second electrode surfaces. An output signal is provided from a temperature sensor, the output signal relating to a temperature within the FAIMS analyzer region. In dependence upon the output signal, the temperature within the FAIMS analyzer region is controllably affected. The apparatus supports operation of FAIMS at temperatures different from the temperature of other components in a tandem multi-stage system, and supports the stable operation of FAIMS at different temperatures which increases the separation capability of FAIMS.
