• mass
  • It is concluded that secondary ionization is not important in the mass spectrometer, and that charge exchange reactions and other related types of reaction, in so far as they occur inside the spectrometer, largely reflect similar reactions occurring in the external flame.

  • system
  • These hydrates occur to a large extent in the cooler parts of the flame system (just before the reaction zone), and are considered to be a secondary phenomenon, possibly formed by association just inside the entry leak into the spectrometer. (royalsocietypublishing.org)
