8.5 Tips
8.5.1 Choosing Suitable Standard Solutions
Various combinations of calibration standard solutions are available to
optimally cover the expected concentration cycles. Sartorius recommends
connecting a higher concentrated standard than standard1.
Depending on the process conditions and the objective of the cultivation,
various concentration ranges have to be covered. The concentration range
should principally be between the concentrations of the standard solutions in
order to ensure optimal measuring accuracy. Furthermore, we recommend
always choosing a standard with very low concentration in order to properly
determine measured values close to zero.
For regulation, the concentrations of the calibration standards should not be
too far from the regulation (set)point. For regulation at 1g/L, for example, it is
more practical to use a combination of 0.5g/L and 4g/L than a combination
of 1g/L and 10g/L, for example.
