Due to its associated process stability and reducing the effect of varying conditions inside the bioreactor, perfusion processes can deliver lower production costs and higher titer, especially in the case of low titer or fragile proteins. One of the most challenging components during perfusion processes is to monitor biomass and viable cell density on-line and in real time, a critical process parameter that significantly impacts the critical quality attributes of the process/product.
