8. Select the Reagent Ion from Vial 1 or Reagent Ion from Vial 2 check box, whichever
appears and is available.
9. Click Start .
A plot of the reagent ion intensity appears ( Figure 13 ). You can observe:
• The response of the reagent ion intensity to changes in the lens parameters in the
Reagent Ion Optics dialog box ( Figure 11 on page 20 )
• The emission current, CI gas pressure, and electron energy in the Reagent Ion Source
dialog box ( Figure 8 on page 16 )
Adjust these parameters to achieve the maximum reagent ion signal intensity.
