AUTOMATED POSITION CONTROL OF A SURFACE ARRAY RELATIVE TO A LIQUID MICROJUNCTION SURFACE SAMPLER

摘要

A system and method utilizes an image analysis approach for controlling the probe-to-surface distance of a liquid junction-based surface sampling system for use with mass spectrometric detection. Such an approach enables a hands-free formation of the liquid microjunction used to sample solution composition from the surface and for re-optimization, as necessary, of the microjunction thickness during a surface scan to achieve a fully automated surface sampling system.
