Tridex has not yet been integrated with an automated sampling system sampling from a perfusion bioreactor. However, the analyzer is triggered by the sampling system so as long as the sample is cell free and the titer is within the range of detection (0.1 -10 g/L) Tridex would be a good fit for a perfusion process. If samples are injected manually then measuring titer with Tridex is the same for batch or perfusion processes.
