White Paper: How Does PAT Apply to the Bioreactor?
Applying Process Analytical Technology (PAT) at the Bioreactor
The bioreactor is the central point where PAT principles are translated into measurable and controllable process variables. Within a Quality‑by‑Design (QbD) framework, PAT links Critical Quality Attributes (CQAs) to Critical Process Parameters (CPPs) and Key Performance Indicators (KPIs) to support consistent and reproducible biopharmaceutical manufacturing.
Our white paper explains how these concepts are applied in practice at the bioreactor, and how they are used in biopharma R&D and GMP environments.

Critical Process Parameters and Key Performance Indicators at the Bioreactor
Download our White Paper to learn the importance and monitoring methods for achieving the optimal product quality and yield.
pH
pH is a Critical Process Parameter that directly influences cell viability, metabolic activity, and product quality. Maintaining pH within the defined operating range is essential for stable bioreactor performance.
Dissolved Oxygen
Dissolved oxygen control is required to balance Oxygen Transfer Rate (OTR) and Oxygen Uptake Rate (OUR), ensuring sufficient oxygen availability without introducing oxidative stress.
Dissolved Carbon Dioxide
Dissolved CO₂ impacts pH buffering, cellular metabolism, and product titer. Monitoring this parameter helps prevent growth inhibition and scale‑dependent variability.
Viable Cell Density
Viable Cell Density is a Key Performance Indicator that reflects culture health and productivity, supporting informed feed and process control decisions.
Total Cell Density
Total Cell Density provides insight into overall biomass accumulation, complementing viability measurements to improve process understanding.
