Calculation:
For each standard solution, the response factor of each compound is calculated as follows:
R = A x M°
M x A°
R
=
response factor of the compound
M =
weight of the compound in mg/50 cm 3
A =
peak area of the compound
M° =
weight of IS in mg/50 cm 3
A° =
peak area IS
For each compound a calibration curve of the type, y=ax, will be obtained. With this curve all the
concentrations of the compounds present in the sample can be calculated. (r2= min 0.995)
Formula:
C = M° x A x 100
a A° W
C = concentration of the compound in mg/100 g sample
A = peak area of the compound
M° = weight of IS in mg/50 cm 3
A° = peak area IS
W = weight of sample in g/50 cm 3
The reintegration and calculations are performed with the software ATLAS or similar.
