Abstract

An apparatus for automated determining of at least two different process parameters of a process liquid of a process, especially a bioprocess, comprising: a first measuring cell, which is embodied to provide a first measurement signal dependent on a first process parameter of a first sample of the process liquid; a second measuring cell, which is embodied to provide a second measurement signal dependent on a second process parameter of a second sample of the process liquid; and a control and evaluation system, which serves for monitoring and/or controlling the process, and which is embodied to receive and to process the first and second measurement signals, especially based on the first measurement signal to determine a measured value of the first process parameter and based on the second measurement signal to determine a measured value of the second process parameter; wherein the first measurement signal and the second measurement signal serve different functions in the context of the monitoring and/or controlling of the process. The first process parameter can be a control parameter (critical process parameter, CPP), and the second process parameter can be a product quality param…
