• The full report Full report essentially contains the same parts as that
of the TESTPb.mth method with standard addition (see section 4.2.6).
However, the following sections are different:
1 Data for substance Only the substance name Pb is given, the other
evaluation parameters remain blank as they are not calcula-
ted when the calibration curve is recorded.
2 Data for calibration Offset Y.offset and slope Slope of the
curve calibration curve.
3 Final results The final result is not calculated as the variable
MC:Pb is not calculated when the calibration
curve is recorded.
• Finally, the calibration curve is printed out:

• The printout of the calibration curve essentially contains the same parts
as the
TESTPb.mth
method with standard addition (see section 4.2.6).
However, the following sections are different:
1 Data for calibration curve Curve type, addition mode, slope of the calibration
curve, offset Y.offset of the calibration curve,
mean deviation of the measured values about the
calibration curve.
2 Calibration curve Measured points (mean values of the measured
peak currents for the calibration solutions),
calculated calibration curve, current axis, axis for
effective mass concentration in the measuring
vessel.
