Capture probe

A system for sampling a sample material, comprising:

• a probe comprising an outer probe housing having an inner wall and an open end configured to communicate with a sample space;
• a liquid supply conduit within the housing and having an outlet positioned to deliver liquid to the open end of the housing;
• an exhaust conduit within the housing configured to remove liquid from the open end of the housing;
• the liquid supply conduit being connectable to a liquid supply configured to deliver liquid at a first volumetric flow rate to the open end of the housing;
• a liquid exhaust system in fluid connection with the liquid exhaust conduit configured to remove liquid from the liquid exhaust conduit at a second volumetric flow rate, the second volumetric flow rate exceeding the first volumetric flow rate, whereby gas containing sample from the sample space will be withdrawn with liquid flowing into and through the liquid exhaust conduit;
• and
• a gas guide positioned between the open end of the probe and a sample, the gas guide comprising tangentially oriented guide ports configured to focus a flow of gas into the liquid exhaust conduit in a cyclonic pattern.
