摘要： A method and system (20) for formation and withdrawal of a sample from a surface (22) to be analyzed utilizes a collection instrument (24) having a port (37) through which a liquid solution is conducted onto the surface to be analyzed. The port is positioned adjacent the surface to be analyzed, and the liquid solution is conducted onto the surface through the port so that the liquid solution conducted onto the surface interacts with material comprising the surface. An amount (52) of material is thereafter withdrawn from the surface. Pressure control can be utilized to manipulate the solution balance at the surface to thereby control the withdrawal of the amount of material from the surface. Furthermore, such pressure control can be coordinated with the movement of the surface relative to the port of the collection instrument within the X-Y plane.

摘要： A system (20) 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 micro junction used to sample solution composition from the surface and for re-optimization, as necessary, of the micro junction thickness during a surface scan to achieve a fully automated surface sampling system.

摘要： Disclosed are systems and methods that include a flow-cell that includes porous conductive material(s) that provides a working electrode(s), an inlet connected to the flow-cell to deliver a solution containing an analyte(s), an outlet connected to the flow-cell to allow the solution to exit the flow-cell, a counter electrode positioned proximate to the outlet, and a voltage source(s) coupled to the working electrode(s) and the counter electrode. The methods can include delivering a solution containing an analyte(s) through an inlet to a flow-cell that includes porous conductive material(s) that provides a working electrode(s), connecting the flow-cell to an outlet for allowing the solution to exit the flow-cell, placing a counter-electrode proximate the outlet, and supplying a voltage from a voltage source(s) to the working electrode(s) and/or the counter-electrode.
