Date of calibration

Date and time of the calculation of the calibration curve for the internal
standard.

Technique

none, std.add., cal.crv., int.std.; none

Calibration technique = Internal standard (

int.std.

)

With the internal standard method, a known quantity of a reference
substance (r) is added to the analysis solution (see section 6.9.6). The
mass concentration

Mass conc.

of the analyte (a) is calculated

as follows from the ratio of the two evaluation values

and the

proportionality factor

Prop.fact.

determined beforehand by meas-

urement of various standard solutions:
