B.3.1 Concentration analysis with response factor
Calibration
The concentration calculations discussed as follows require a unique
response factor for each component in an analysis. These factors may be
manually entered by an operator or automatically calculated by
calibrating the system.
where
Calculated response factors are stored by the GC for use in the
concentration calculations, and are printed out in the configuration and
calibration reports.
