Creating a Method
4 Select the box, Rejected Masses and enter the masses for which background
spectrum you do not want subtracted.
The background spectrum for the masses you edited in the Rejected Masses box will
not be subtracted. It is used when you do not want to subtract the spectrum for spe-
cific masses; for example the spectrum for internal standards.
NOTE Subtract Background is used to subtract a background spectrum from a sample
spectrum. When Subtract Background is selected, the abundance values for each
mass in the background spectrum are subtracted from the abundance values of the
corresponding mass in the sample spectrum. Subtract Background is different from
Blank Subtraction available in Data Analysis where the blank quantitative results are
subtracted from sample quantitative results.
5Click Interference Correction.
Any interference correction equations stored in a given method will be used to cor-
rect all data acquired by that method, if Interference Correction is selected.
6 To set the corrections you have chosen, click OK.
The Select Reports dialog box appears.
