Abstract
A system for introducing a sample to an analyzing device, such as a spectrometer, wherein the flow rate of gas to the analyzing device is maintained substantially constant and uncontaminated during sample changeover. The system includes a flow controller and flow control paths arranged to avoid having any flow diverting valves or direction change in the analyte flow path.
