摘　　要：The mass spectrometer and the method of measuring concentration of oxygen in the region of mouth and nose in vivo experiment under low pressure were developed. A mass flow controller was assembled through the inlet capillary of MGA-1100 mass spectrometer. The mass flow controller was controlled by a computer controlled the operating pressure in MGA -1100 to make operating in its linear region. The measuring value is not affected from the pressure of inlet. MGA-1100 mass spectrometer with improved inlet system can reach the demand of most human experiment under low pressure.
