Claim 3:
4. A method for analyzing droplets, comprising:
providing a probe comprising an outer probe housing having an open end;, providing a liquid supply conduit within the outer probe housing having an outlet positioned to deliver liquid to the open end of the outer probe housing, the liquid supply conduit being connected to a liquid supply for delivering a liquid at a first volumetric flow rate to the open end of the outer probe housing, and a liquid exhaust conduit within the outer probe housing for removing liquid from the open end of the outer probe housing, wherein the liquid exhaust conduit comprises a tubular conduit positioned within the outer probe housing, and wherein the liquid supply conduit is defined by the annular space between the liquid exhaust conduit and an inner wall of the outer probe housing;
providing a liquid exhaust system in fluid connection with the liquid exhaust conduit for removing liquid from the liquid exhaust conduit at a second volumetric flow rate;
providing a droplet dispenser for dispensing drops of a liquid sample or a sample-containing solvent into the liquid at the open end of the housing;
providing a chemical analysis instrument;, flowing liquid through the liquid supply conduit at the first volumetric flow rate to the open end using a pump and drawing the liquid into and through the liquid exhaust conduit at the second volumetric flowrate;, dispensing the drops from the droplet dispenser into the liquid at the open end;, analyzing the liquid from the liquid exhaust conduit in the chemical analysis instrument.
