Surface layer disruption and ionization utilizing an extreme ultraviolet radiation source
A surface ionizer for a trace detection system includes an extreme ultraviolet light source and an ion transfer line. Activation of the extreme ultraviolet light disrupts a surface of a sample along with residue and ionizes the resulting vapor. The ionized vapor is collected in the ion transfer line and passed into an analysis device for detection of components in the vapor.
Multiple gas flow ionizer
An ionizer includes a probe having multiple coaxially aligned conduits. The conduits may carry liquids, and nebulizing and heating gases at various flow rates and temperatures, for generation of ions from a liquid source. An outermost conduit defines an entrainment region that transports and entrains ions in a gas for a defined distance along the length of the conduits. In embodiments, various voltages may be applied to the multiple conduits to aid in ionization and to guide ions. Depending on the voltages applied to the multiple conduits and electrodes, the ionizer can act as an electrospray, APCI, or APPI source. Further, the ionizer may include a source of photons or a source of corona ionization. Formed ions may be provided to a downstream mass analyser.

High resolution imaging apparatus and method
The present invention relates to the high resolution imaging of samples using imaging mass spectrometry (IMS) and to the imaging of biological samples by imaging mass cytometry (IMC?) in which labelling atoms are detected by IMS. LA-ICP-MS (a form of IMS in which the sample is ablated by a laser, the ablated material is then ionised in an inductively coupled plasma before the ions are detected by mass spectrometry) has been used for analysis of various substances, such as mineral analysis of geological samples, analysis of archaeological samples, and imaging of biological substances. However, traditional LA-ICP-MS systems and methods may not provide high resolution. Described herein are methods and systems for high resolution IMS and IMC.
System and Method for Loading an Ion Trap
Systems and methods for loading microfabricated ion traps are disclosed. Photo-ablation via an ablation pulse is used to generate a flow of atoms from a source material, where the flow is predominantly populated with neutral atoms. As the neutral atoms flow toward the ion trap, two-photon photo-ionization is used to selectively ionize a specific isotope contained in the atom flow. The velocity of the liberated atoms, atom-generation rate, and/or heat load of the source material is controlled by controlling the fluence of the ablation pulse to provide high ion-trapping probability while simultaneously mitigating generation of heat in the ion-trapping system that can preclude cryogenic operation. In some embodiments, the source material is held within an ablation oven comprising an electrically conductive housing that is configured to restrict the flow of agglomerated neutral atoms generated during photo-ablation toward the ion trap.
ION ANALYZER
An ion analyzer includes: a sample placement unit 2 on which a sample 1 is to be placed; an excitation beam irradiation unit 3 that irradiates the sample 1 placed on the sample placement unit 2 with an excitation beam in a direction perpendicular to a surface of the sample 1; a deflection unit 6 that makes at least some of ions generated from the sample 1 to fly in a direction deviating from an irradiation path of the excitation beam; and an analysis unit 8 disposed in a flight direction of ions deflected by the deflection unit 6, that separates and measures the ions in accordance with a predetermined physical quantity.
