1. a gas phase molecular absorption spectrometer comprises sampling device, gas-liquid separation device, drying device and pick-up unit, it is characterized in that,Described gas-liquid separation device comprises injection port (1), reaction chamber (2), gas vent (3), linker outlet (4), waste liquid row mouthful (5) and air pressure balance mouth (6),Described injection port (1) is communicated with described reaction chamber (2), described reaction chamber (2) is communicated with described waste liquid row mouthful (5) and air pressure balance mouth (6) by described linker outlet (4), described gas vent (3) is positioned at the top of described reaction chamber (2) and is communicated with the input of described drying device, described injection port (1) also is communicated with the output of described sampling deviceIn gas phase molecular absorption spectrometer sample test process, the mixed solution after the heating enters into reaction chamber (2) from injection port (1) under the effect of carrier gas, because action of gravity, liquid in the mixed solution flows out downwards, export (4) outlet through linker, from waste liquid row mouthful (5) mouthful dischargeEnter steam in the mixed solution of reaction chamber (2) and gas from reaction chamber (2) top, overflow through gas vent (3) outlet,Because liquid level and linker outlet (4) outlet maintenance level in the principle of linker, reaction chamber (2), the excess liquid that enters reaction chamber (2) is discharged through linker outlet (4) outlet,The hollow pipe of air pressure balance mouth (6) for communicating with the external world is in order to the inner and outer air pressure of balance gas-liquid separation device.
