Abstract
In a sampling system for mass spectrometry, a method and apparatus are set forth for high flow-rate flushing and sample delivery via a sampling probe (). The sampling system includes a sampling probe () having a first fluid conduit () with an inlet, a second fluid conduit () with an outlet, and a sampling port fluidly connecting the first fluid conduit () and second fluid conduit (). A fluid source () is attached to the inlet and a vacuum source () is attached to the outlet for causing fluid to flow through the first fluid conduit () past the sampling port and exit through the second fluid conduit (). A cap () is provided for selectively closing and opening the sampling port. When the cap is removed, thus when the sampling port is open, sample may be introduced into, and captured by fluid flowing through the sampling port. When the cap is in place, thus when the sampling port is closed, a flushing fluid is supplied for flushing the sampling probe ().
