Enable Manual Integration – this
tool activates the manual integration toolbar.
Clear Manual Integration – this tool
becomes active once a manual
integration is present.
Zero Peak – this tool sets start and
stop to the same value.
Merge Right/Left Peak – this tool
merges the peak to the right/left of
the selected peak.
Split Peak and Pick Right/Left –
this tool splits the peak and then
selects the right or left peak.
Snap Baseline – this tool places
start/stop integration points on the
baseline.
Drop Baseline – this tool finds the
lowest end of the peak, then drops
the baseline on the other side of the
peak from it, thereby creating a flat
baseline that avoids negative area.

Compound InformationPeak Annotation
Activated from Tools > Add-Ins…
NI – The peak was not integrated at all by the
computer software.
LT – The peak in question was inappropriately
integrated to an area less than what it should be
(e.g., Peak area was cut).
GT - The peak in question was inappropriately
integrated to an area greater than what it should be
(e.g., Peak Tailing).
BA – The baseline had to be adjusted correctly by the analyst.
CO –The analyst had to split to co-eluting peaks apart that were not (or could
not be) separated by the computer system.
RT – The retention time for the peak in question has shifted from the expected
retention time.
INT – There was electronic interference (e.g., Noise).

Globals SettingsCalculated and Final Concentration
Calculated Concentration (Calc. Conc.)—is the concentration of the
compound as calculated from the calibration curve.
Final Concentration (Final Conc.)—is the concentration after the
Multiplier has been applied to the Calculated Concentration.
The equations are:
Final Concentration = Calculated Concentration x Multiplier

Used with Stream Select (LC)
When the Bracketing Type Sample Group is implemented, only samples
from a specific Sample Group (specified in the Batch Table) are considered
in the formation of the calibration curve and quantitation of the samples. This
feature would accommodate slight shifts in retention time and/or variations
in instrument responses.
Added from Worklist or Batch Table.

MassHunter Webinar Series
The Reference Library is activated from Library
> Setup Reference Library…
A reference library can be created from a
calibrator or existing library and added to the
quant method to aid in the identification of
compounds.
High level calibrator
should be selected before
entering Method Editor to
obtain better quality
spectra for the reference
library from the sample.

MassHunter Webinar Series
Standard Addition is activated in Globals Setup in the Method Editor.
The calibration curve is Linear, Ignore Origin and No Weighting.

Quant assumes that the order samples are acquired are the order in which
they are analyzed.
Order in Batch Table is imperative.
