RESUMEN
This paper explained the working method of the quadrupole mass spectrometer array and its features of volume, weight, power, sensitivity to many kinds of gases as well as flexibility when used together with a miniature gas chromatograph (GC) and a thermal-conductivity detector (TCD). Three types of structure formed in its development are also described. Finally, the applications of the quadrupole mass spectrometer array in the field of manned spaceflight were summarized.

Environmental control and life support system (ECLSS) is a critical subsystem of manned spacecraft that has the most typical characteristics of manned space flight. It is an indispensable safeguard for the life of astronaut in space. This article reviewed the main techniques and developments of oxygen and water closed loop recycling in regenerative environmental control and life support system. Through comparing and analyzing the current state of its space application as well as the strong and weak points of different technique routes, the directions of research and development of oxygen and water recycling technique for space station are proposed.
