Meaning of the individual factors:
W: Weight of the sample in g
Fa: Soluble foreign-matters portion in %
Fb: insoluble foreign-matter portion in %
Fc: Conversion factor for it unit
g/l
mg/l und ppm
g/100 ml
%
Fd: Target concentration of the solution to be prepared in g/l, mg/l (ppm), g/100 ml, or %
Fe: Specific weight of the weighted-in sample in g/cm³
Ff: Volume correction in ml. this volume correction is the required surplus dosage for compensating the
volume contraction and the specific-weight difference between the sample weight and the solvent (please
observe the note on volume correction)
Fg: Specific weight of the solvent used in g/cm³
Note on volume correction:
The user has to decide on a case-by-case basis whether a volume correction is necessary and according to
which procedure this correction is to be performed. As a rule, this volume correction may be omitted in the case
of solutions with very low percentages of diluted substance.
