Figure 7-34 Target Percentage Low
3b If the red box is in the Max Target Percentage, the Target Resolution needs
to be decreased. Use increments of 0.05 to make changes to the Resolution. If
the Target Resolution reaches 0.9, proceed to
Step 4 and follow with Step 4c ,
if needed.
4 Check to see if the mass percentage is in range. (Red box has disappeared.)
4a If the Resolution is in range, proceed to Step 4 , section 7.6.3, Adjusting the Ion
Energy, on page 7-30 .
4b If the Min or Max Target Percentage is red and the Target Resolution is within
0.9 and 1.10, repeat
Step 3 and Step 4 until the masses all no longer show red.
4c If the Min or Max Target Percentage is red, more adjustments need to be
made. If the Target Resolution is at the low end of the range (0.9) and mass
percentage still needs to be lowered, the Ion Energy will need to be adjusted.
If the Target Resolution is at the high end (1.10) and the mass percentage is
not OK, an Ion Energy adjustment is also needed. Proceed to
section 7.6.3 .
7.6.3 Adjusting the Ion Energy
1 Prior to performing this procedure, follow the steps outlined in section 7.6.1,
Adjusting Base Peak Gain, on page 7-25 and section 7.6.2, Adjusting
Resolution, on page 7-29 .
