7.12 Calibration
A calibration must be performed to quantify a peak (i.e., determine the amount of
a sample based on known standard gases). In this section, the procedure for
setting up single level and multiple level calibration is described.
7.12.1 Obtain Preliminary Data for Calibration
To enter calibration peak data, run a sample of a calibration gas (i.e., a sample with
known component concentrations). The generated data file can be used to define
the calibration peaks.
1
Click
Control >> Single Run to run the sample.
2
Type the desired Sample ID and click Start.
3
After the run is complete, ensure all peaks are integrated and annotated.
7.12.2 Enter Concentration Amounts in the Peaks/Groups Table
The known concentration of components in the calibration gas must be recorded in
the Peaks/Groups table.
NOTE: If calibration concentrations were entered when defining single peaks
), this step can be skipped.
1
Click Method >> Peaks/Groups.
2
Use the scroll bar to scroll until the Level 1 column is visible. See
Figure 7-46 Level information in the peak table
3
Type the concentration of the component.
4
Repeat this for all peaks and groups in each of the channels.
