In various embodiments, a device may generally comprise a remote ablation chamber comprising an inlet and an outlet, a laser to deposit energy into a sample in the chamber to ablate the sample and generate ablation products in the chamber, a transport device in fluid communication with the outlet, an ionization source to ionize the ablation products to produce ions, and a mass spectrometer having an ion transfer inlet to capture the ions. The ablation products or the ions may be transported in a fluid stream from the ablation chamber through the transport device.

Mass spectrometer


The present disclosure provides a mass spectrometer for performing an analysis of sample ions, and a method for operating a mass spectrometer. The mass spectrometer comprises a first ion optical element that is supplied with a first gas; a mass analyzer, wherein the performance of the mass analyzer is dependent on the pressure of the first gas in the first ion optical element; and a controller for setting a property of the first gas, which comprises at least the pressure of the first gas, on the basis of a characteristic of the analysis to be performed by the mass spectrometer..

High duty cycle ion spectrometer


An ion spectrometer is provided, comprising: an ion source, arranged to generate ions continuously with a first range of mass to charge ratios; and an ion trap, arranged to receive ions from the ion source along an axis, and to eject ions with a second range of mass to charge ratios orthogonally to that axis, the second range of mass to charge ratios being narrower than the first range of mass to charge ratios. In some embodiments, ions generated by the ion source continuously flow into the ion trap.
