Learning Outcomes and Competencies Students will
  • be able to transfer the principles of laboratory analytics to process; analytics (continuous real-time acquisition, signal conversion)
  • be able to set up, characterise, calibrate and apply a measurement chain;
  • be able to determine and document measurement results, including the measurement uncertainties contained therein;
  • become familiar with the online measurands important in bioprocesses (pH, pO2, conductivity, glucose) and be able to assess their relevance in biotechnological applications;
  • be able to use typical sensors for bioprocesses (e.g. potentiometry, amperometry, optical sensors, conductive LF measurement) and infer their requirements for the measurement technology;
  • be able to commission, configure, operate and maintain the sensors and the associated measurement technology as well as evaluate and correctly document the measurement data.
Module Content Measurement technology
  • Setting up a measurement chain (from sensor to signal)
  • Determining the transmission behaviour of a measurement chain (theoretically and with calibration)
  • Basic principles of signal conversion (including A/D signal conversion, multimeter)
  • Measurement deviations, error calculation, error propagation
Sensor technology
  • pH measurement with process sensors, application of digital sensors, calibration, characteristic curve
  • Design, application and operation of optical pH sensors, comparison with potentiometric electrodes
  • pO2 measurement: comparison of optical and amperometric measuring principle, calibration, characteristic curve
  • Non-reversible biosensors: measuring principle and application (glucose test strips)
  • Connection, configuration and operation of an analogue current output on a process measuring amplifier
  • Application of ion-selective electrodes
  • Application of glucose biosensors in a model bioreactor, control of the glucose feed
