Offline OD vs. Online Backscatter – A technology review

We often receive the question: “Does the CGQ measure optical density (OD)?”. The answer to this question is “No, it measures backscatter”. Automatically, this leads to many follow up questions: “What is backscatter? How can it be used to measure biomass? And what are the advanatages/disadvantages of backscatter measurements compared to OD measurements?”

Together with our global distributor INFORS HT we have written a brief review to answer all of these questions. You can find the review on the INFORS HT Blog: Measuring Biomass in Shake Flasks: Offline OD vs. Online Backscatter Light
