Measuring gap (optical
layer thickness)
Nitrate measurement,
1 mm gap width
Nitrate measurement,
5 mm gap width
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 signifi-
cantly influenced by the light scattering due to solids and the absorption
of accompanying substances (sample matrix). Therefore, no fixed
measuring range can be determined beforehand.
