The quoted measuring ranges are nominal measuring ranges that
are theoretically possible. In practice, real measuring ranges exist
that are given by the limits of photometric determination. The limits
are significantly influenced by the light scattering due to solids and
the absorption of accompanying substances (sample matrix).
Therefore, no fixed measuring range can be determined before -
hand.
