A system, apparatus configured to dynamically vary an extraction distance between an extraction volume and a sample surface through a probe assembly height adjustment apparatus operably coupled to a motor in which a processor can move the probe assembly height adjustment apparatus to maintain the extraction distance, or tune the extraction distance to optimize sampling performance. Methods for calibrating, tuning an extraction distance between an extraction volume and a sample surface.

Apparatus for dynamically varying extraction distance between extraction volume and sample surface

A laser ablation probe comprises a tubular element adapted for conducting a carrier fluid in a substantially laminar flow. The tubular element comprises a fluid inlet and a fluid outlet arranged at opposite end portions of the tubular element for enabling the carrier fluid to flow through the tubular element. The tubular element further comprises a central portion having an aperture defined therein for admitting an aerosol generated by laser ablation from a material sample into the carrier fluid flow when this sample is positioned outside the tubular element at a distance in the range of 0 &#x3bc;m to 100 &#x3bc;m from the aperture.
