I would like to ask why the impurity content values obtained using an Agilent gas chromatograph are higher than the actual values

How was the conclusion reached that the impurity content data analyzed by the Agilent gas chromatograph were higher than the actual value?
The chromatography column is not clean or there is high noise (the equipment or the air is not clean)
It’s caused by improper settings for the integration events; adjusting the workstation settings will fix it
The columns have been rinsed with methanol many times
Is it higher than the actual value because of the standard sample used for measurement, or compared to previous values, or is it higher than the theoretical or empirical values? Are the corrected data higher, or are the uncorrected data higher?
