Figure 14 Quadratic Calibration Curve
Storing Multiple Points
As good analytical practice, standards for multiple point calibrations should be run
and stored in the library in order of increasing concentration.
When a calibration is performed, only one point will be used to update the
calibration curve that you have created. All of the points on the curve are updated
based on the response ratio from the single point, contained in the calibration gas.
Ideally, you will choose a point in the middle of the calibration curve as the
concentration to be included in the calibration gas.
For high accuracy applications, you may want to do multiple point calibration on a
daily basis.
1. Select the correct column for your compounds.
If your compounds of interest must be run on more than one column, you must
store information for one column at a time.
2. Connect your sample and press Start Stop to begin an analysis.
