*Other lines of appropriate sensitivity, free of interferences or corrected for interferences in specific matrixes may be as just as
acceptable.
B.3
Quantification
B.3.1 General
As spectroscopic techniques are not able to measure concentrations directly, but by means of a
conversion of the emission signal into concentration, calibration is inevitable. Calibration can be
performed by means of a calibration curve.
B.3.2 Calibration curve
A calibration curve is constructed by adding increasing amounts of the substance to be studied to a
solution of a supporting matrix. The most difficult condition to meet is making the solutions used for
