Abstract

PURPOSE:To enable high speed and accuracy analysis by providing an orifice at the gas induction section, forming an exhaust passage near it using an upward inclined wall, providing a vacuum chamber below the orifice, and arranging a pair of right and left quadruple type mass spectrometers crossing this chamber. CONSTITUTION:An orifice 3 is provided at the sample gas induction section in a gas analyzer 1 and a gas exhaust passage 5 which is bent upward is formed at the upper vicinity using an upward inclined wall 5a. The passage 5 is connected to an absorption pump 4 and gas is discharged in the air. A vacuum chamber 8 which is connected to a vacuum pump is formed at the lower part of the orifice 3 by combining a scattering pump 6 with an absorption pump 7 and a pair of right and left quadruple type mass spectrometers 11a and 11b are connected to this vacuum chamber crossing the chamber 8. Besides, the first and second on and off valves 9 and 10 are provided in the vacuum chamber 8. As a result, high speed and accuracy analysis can be made.
