Abstract
Method for titration comprising: providing a solution comprising at least one titrand and at least one indicator; providing a titrant; performing titration by repeatedly: transmitting light through the solution; measuring an intensity of light transmitted through the solution at a first wave length; measuring an intensity of light transmitted through the solution at a second wave length; comparing the measured intensities of light transmitted through the solution at the first and second wave lengths with a target value; and adding titrant to the solution at a rate based on said comparing.

Method for titration, comprising,
- providing a solution comprising at least one titrand and at least one indicator
- providing a titrant,
- performing titration by repeatedly:
- transmitting light through the solution,
- measuring an intensity of light transmitted through the solution at a first wave length,
- measuring an intensity of light transmitted through the solution at a second wave length,
- comparing the measured intensities of light transmitted through the solution at the first and second wave lengths with a target value, and
- adding titrant to the solution at a rate based on said comparing.
Apparatus for titration comprising,
- a titration vessel, a detector, a light source, a titrant dosing device, and a control device, wherein
- the titration vessel is arranged to hold a solution comprising at least one titrand, and to receive a flow of titrant solution from the titrant dosing device,
- the detector is arranged to measure an intensity of light transmitted from the light source through the solution at a first wave length, and an intensity of light transmitted from the light source through the solution at a second wave length, and
- the control device is arranged to compare the measured intensities of light transmitted through the solution at the first and second wave lengths with a target value, and to control the flow of titrant solution from the titrant dosing device at a rate based on said comparing.
