Claim:
1. A system for sampling a sample material, comprising: a probe comprising an outer probe housing having an open end; a liquid supply conduit within the housing and having an outlet positioned to deliver liquid to the open end of the housing, the liquid supply conduit being connectable to a liquid supply for delivering liquid at a first volumetric flow rate to the open end of the housing, and a liquid exhaust conduit within the housing for removing liquid from the open end of the housing; 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, the first volumetric flow rate exceeding the second volumetric flow rate, wherein during operation of the system liquid at the open end receives sample material, liquid containing sample material is drawn into and through the liquid exhaust conduit, and liquid overflows from the open end; and, an overflow collection system for collecting the overflow liquid from the open end of the probe.
