• 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 Substance name, mass concentration Mass
evaluation conc. found and its absolute and relative total
deviation MC.dev., the deviation due to the
calibration Cal.dev., substance mass Mass
found in the measuring vessel and sample volume
V0.sample in the measuring vessel.
2 Data for calibration Offset Y.offset and slope Slope of the
curve calibration curve used for the calculation.
3 Final results Final result with formula calculation.
