Measurement of biocide residuals
After reading this article you will..
- understand that measurement of biocide recidual enables optimisation of biocide dosing.
- know that some oxidising biocides are rather easy to measure directly from process samples .
- know that the measurement of non-oxidising biocides requires usually advanced analytics. It can be done in a well-equipped laboratory, for example, in order to verify food-contact compatibility of a dry paper product.
