Reactor Dynamics Investigation Based On Calorimetric Data

Thierry Meyer, Francis Stoessel, Michal Dabros, Charles Ibrahim Guinand

A simple and general procedure has been developed to determine the thermal behaviour of a reactor based on heat balance, PID temperature control, and jacket behaviour. Using only temperature heating/cooling ramps followed by isothermal stages, such a proce ...

Cole-Cole, linear and multivariate modeling of capacitance data for on-line monitoring of biomass

Urs von Stockar, Ian William Marison, Michal Dabros, Danielle Dennewald

This work evaluates three techniques of calibrating capacitance (dielectric) spectrometers used for on-line monitoring of biomass: modeling of cell properties using the theoretical Cole-Cole equation, linear regression of dual-frequency capacitance measure ...

Springer-Verlag2009

The recent phenomenal growth of the field of biotechnology has contributed to a mounting pressure to improve process efficiency and productivity and to increase the quality and safety of end-products. This demand gave rise to the discipline of on-line biop ...

On-Line Recalibration of Spectral Measurements Using Metabolite Injections and Dynamic Orthogonal Projection

Urs von Stockar, Michael Amrhein, Pamandeep Singh Gujral, Michal Dabros

Spectrometers are enjoying increasing popularity in bioprocess monitoring due to their non-invasiveness and in-situ sterilizability. Their on-line applicability and high measurement frequency create an interesting opportunity for process control and optimi ...
