摘要： A method for creating a trench with a defined intended trench depth in a sample uses a particle beam system configured to create a particle beam to ablate material from the sample. An exemplary method comprises: defining a particle beam system setting which is a setting of the particle beam system for implementing an ablation unit step with the particle beam; acquiring calibration data records using the defined particle beam system setting on a calibration sample; determining a regression curve based on the acquired calibration data records, the regression curve being defined on the basis of at least one parameter that characterizes the ablation unit step; determining an implementation number based on the determined regression curve and the intended trench depth; and creating a trench in the sample by repeatedly implementing the ablation unit step with the particle beam system setting in accordance with the determined implementation number.

摘要： Chemical composition of liquid phase samples is determined based on laser induced ablation spectroscopy of droplets. An aerosol jet comprising a carrier gas and liquid phase sample droplets, less than about 10 microns in diameter, is formed. An emissive plasma plume is generated from the sample droplets using a pulsed laser to deposit energy at a focal point in the aerosol jet. Light from the plasma plume is gathered with a concave mirror and focused into one end of a fiber optic lightguide. The lightguide can transmit spectral emissions from the plume to a spectrometer/detector which can send wavelength and intensity values to a computer. The computer is operable to determine a liquid sample composition based on the wavelength and intensity values.
