Characterization method for a new diffusion mixer applicable in micro flowinjection analysis systems

A new mixer is designed for mixing a phenolic solution into water. The mixe r design is such that it can be easily adjusted for the controlled mixing o f a specific compound within a certain time. This paper describes the worki ng principle of the mixer as well as a suitable characterization method for the mixer. Measurement results are presented which show the correct workin g of the mixer. A quantitative measure is introduced to express the extent of mixing performed by the mixer. The characterization method allows the me asurement of the flow rate, pressure drop and extent of mixing.
