  • Page 128: To Use Other Reagent Gases

    Changing the reagent gas from methane to either isobutane or ammonia changes the chemistry of the ionization process and yields different ions. The principal CI reactions encountered are described in general in the 5977C Series Concepts Guide. If you are not experienced with CI, we suggest reviewing that material before you proceed.
  • Page 129 Operating in CI Mode To Use Other Reagent Gases Isobutane CI Isobutane (C ) is commonly used for CI when less fragmentation is desired in the CI spectrum. This is because the proton affinity of isobutane is higher than that of methane; hence, less energy is transferred in the ionization reaction. Addition and proton transfer are the ionization mechanisms most often associated with isobutane.
  • Page 130 Ammonia tends to break down vacuum pump fluids and seals. Ammonia CI makes more frequent vacuum system maintenance necessary. Refer to the Agilent 5977C Series MSD Troubleshooting and Maintenance Manual. Frequently, a mixture of 5% ammonia and 95% helium or 5% ammonia and 95% methane is used as a CI reagent gas.
