Calibration

The description of the gas chromatograph calibration process can be found here.

Analysis

• Inject test sample of brandy at least three times.



• Process sample chromatograms.



• Using equation below, calculate the concentration of each congener in the samples.



• As a result of calculations, the values ​​of the concentrations of analytes in the dimension mg/L AA.
