Abstract
An automated sample introduction system for moisture and oxygen analysis includes multiple pneumatic valves, multiple tubing assemblies, multiple solenoid valves, and a control unit. A first pneumatic valve is connected to a clean gas source; a first tubing assembly connects the first and second pneumatic valves; a third pneumatic valve connects to the gas source to be tested; a second tubing assembly connects the second to fifth pneumatic valves to the inlet of a vacuum pump; a third tubing assembly connects the fourth pneumatic valve to the instrument's input port; a sixth pneumatic valve connects to the instrument's output port; multiple solenoid valves are connected to a driving gas source; the driving gas interfaces of the first to sixth pneumatic valves are respectively connected to the multiple solenoid valves; and the control unit is electrically connected to the control contacts of the multiple solenoid valves to control the opening and closing states of each pneumatic valve through each solenoid valve.
