Fig. 36 Adding or modifying isotope correction equations
In the CORRECTION EQUATION field in the ISOTOPES AND EQUATIONS list, enter or edit the
isotope correction equation.
7.3 Calculate isotope ratios
Slightly different acquisition parameters are required in order to make the best isotope
ratio measurements. Typically fast scanning with a longer total acquisition time
delivers the best results. Configure the species for isotope ratio measures, if required.
This is usually not done in routine analysis, but is available for certain specialized
applications.
1. From the main page of the worksheet, click [E
DIT METHOD].
2. Select the I
SOTOPE RATIOS tab.
3. In each
SPECIES column, define the two species for inclusion as a ratio by entering
the appropriate element symbols and their m/z values.
If the m/z value is not entered, a default isotope for the selected element is used.
