ISTD ID #
If you are doing internal standard calibration, enter
the ID # for the internal standard peak for this
compound. This is the peak ID number from the peak
table. If you don’t know it, you can add it in the peak
table later.
Ref ID #
Enter a retention time reference peak ID # to be used
for this peak. This is the peak ID number from the
peak table. If you don’t know it, you can add it later
in the peak table. Reference peaks are used to locate
calibrated peaks when chromatographic conditions
change such that retention times shift.
Retention Time Window
Select how you want to enter the retention time
window for this peak. The window is used for peak
identification in case of slight deviations from the
expected retention time.
Relative
Click this if you want the system to calculate the
retention time window based on a % of the expected
retention time of the peak. Enter the % you want to
use for calculation of the window.
Absolute
Click this if you want to enter an absolute window for
the peak. Enter the value you want to use for the
retention time window, in minutes.
