Description
Label
N
Shows the retention time for the internal standard associated
with the current analyte. For internal standards, or for analytes
without an internal standard, the value is set to N/A.
IS Retention Time
N
Shows the signal-to-noise ratio for the internal standard
associated with the current analyte. For internal standards, or for
analytes without an internal standard, the value is set to N/A.
IS Signal / Noise
N
Shows the start time for the internal standard associated with
the current analyte. For internal standards, or for analytes without
an internal standard, the value is set to N/A.
IS Start Time
N
Shows the total width for the internal standard associated with
the current analyte. For internal standards, or for analytes without
an internal standard, the value is set to N/A.
IS Total Width
N
Shows the width at 50% for the internal standard associated with
the current analyte. For internal standards, or for analytes without
an internal standard, the value is set to N/A.
IS Width at 50%
N
Shows the level of confidence in the isotope ratio. Applicable to
qualitative workflows only.
Isotope Confidence
N
Identifies the difference between the theoretical isotope pattern
(based on the formula) and isotope pattern from the acquired
spectra.
Applicable to qualitative workflows only.
Isotope Ratio
Difference
N
Shows the level of confidence in the Library Hit based on the
Library score of the hit. Applicable to qualitative workflows only.
Library Confidence
N
Shows the compound name of the best library match, that is, the
compound with the highest purity score and the formula matching
the requested formula.
The value is can be updated using data from the Peak Review
Library Search Results grid. Applicable to qualitative workflows
only.
Library Hit
N
Shows the difference between found mass and extraction mass,
expressed in PPM (parts per million) error. Applicable to
qualitative workflows only.
Mass Error (ppm)
N
Shows the level of confidence in mass error. Applicable to
qualitative workflows only.
