  • Raman spectroscopy integrated perfusion cell culture system for monitoring and auto-controlling perfusion cell culture
    Patent number: 11774287
    Abstract: A Raman spectroscopy integrated perfusion cell culture system for monitoring and auto-controlling perfusion cell culture, comprising: a bioreactor, comprising: (1) an interior chamber for receiving a cell culture, (2) a port for feeding nutrient materials from a feed reservoir into the interior chamber, (3) a port for auto-bleeding from the interior chamber, and (4) a port for continuously harvesting materials from the interior chamber with the help of a cell retention system; a Raman analyzer, comprising (i) one or more Raman probes which are immersed into the bioreactor and is configured to collect Raman spectrum in the bioreactor, and (ii) a host computer which is configured to receive the Raman spectrum collected and transferred by the Raman probe and turn it into values; and a controller in communication with the Raman analyzer, the feed reservoir and an auto-bleeding device, the controller being configured to receive the values from the Raman analyzer and compare them with preset parameters, based on re
