• The full report Full report contains not only the usual header (see

section 4.2.6), but also the following important sections:

1 Data for substance Only the substance name Pb is given, the other

evaluation of Pb parameters remain blank as they are not calcula-

ted when the calibration curve is recorded.

2 Data for substance Only the substance name CdRef is given, the

evaluation of Cd other parameters remain blank as they are not

calculated when the calibration curve is recorded.

3 Data for calibration Only the proportionality factor is given.

4 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 calibration curve contains the usual header (see section 4.2.6) and

the following important sections:

1 Data for calibration curve Curve type, proportionality factor Slope, 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 concentrations of analyte and

reference substance in the measuring vessel.
