ON-LINE DETERMINATION OF TRACE AMOUNT OF He IN D_2 MATRIX WITH QUADRUPOLE MASS SPECTROMETER

    Graphical Abstract
    • Abstract
  • An analytical system is developed for the on--line determination of helium in deuterium matrix, in-cluding a gas sampling system, a Zr-Al pump system for deuterium and helium separation, and aquadrupole mass spectrometer. The system established demonstrates a satisfactory detection limits of Heat 4×10~8 He atoms for 0.133 Pa·l single sample injection.
