High flowrate flushing for open port sampling probe

A method of operating a sampling probe that comprises a first fluid conduit having an inlet, the first fluid conduit in fluid communication with a second fluid conduit having an outlet, and a sampling port for receiving and capturing sample fluidily fluidly connecting the first fluid conduit and the second fluid conduit, the method comprising:

• supplying capture fluid to the inlet;
• aspirating the capture fluid from the outlet;
• and,
• controlling the flow of the capture fluid through the sampling port using a cap to selectively close the sampling port and open the sampling port to receive a sample.

A method of sampling, comprising:

• providing a sampling probe including a first fluid conduit having an inlet, a second fluid conduit having an outlet, and a sampling port for receiving and capturing sample between the first fluid conduit and second fluid conduit;
• supplying a capture fluid at the inlet;
• aspirating the capture fluid at the outlet;
• opening the sampling port and supplying capture fluid at a first flow rate to capture samples at the sampling port;
• and
• closing the sampling port and supplying a flushing fluid at a second flow rate higher than the first flow rate for flushing the sampling probe.
