Description
Label
Y
Shows the ion ratio.
• Ion Ratios are determined when at least two MRM transitions
from a single analyte have been collected into a group.
• The first component in a subgroup is used as Quantifier ions.
The remainder of the components in the subgroup are used
as Qualifier ions.
• Ion Ratio = (Peak Area or Height of Qualifier) / (Peak Area or
Height of Quantifier)
• Subgroups
• All of the analytes in a group constitute an Analyte
subgroup.
• All of the internal standards in a group constitute an IS
subgroup.
• If a component is not a member of a group, then the Ion Ratio
value is set to N/A.
• If the peak is not found, then the Ion Ratio value is set to N/
A.
• Applied to all of the components in both of the Analyte and
IS subgroups, the Qualifier is itself for the Quantifier.
• If the integration changes for either of the Quantifier or the
Qualifier peaks, then the Ion Ratio is calculated again.
• Can be calculated for either the peak area or peak height. If
the Area is used in the regression part of a .qmethod for the
first component (Component Index is 1) in the Results Table,
then the peak area is used for the calculation of the Ion Ratio
for the entire Results Table. If the Height is used in the
regression of the first component, then the peak height is
used for the calculation.
Ion Ratio
N
Shows the level of confidence in the Ion Ratio. Applicable to
qualitative workflows only.
Ion Ratio Confidence
N
Shows whether the row is an internal standard. A selected check
box indicates that the component for the row is an internal
standard, not an analyte.
