How It Works

Creation

Select among predefined column templates, or define your own custom columns.

Calibration

Fit model parameters to experimental data. Typically, 5-8 experiments are needed to build a well-fitted model.

Validation

Validate the model accuracy by performing an additional 1-2 experiments, and compare these unseen experiments with the simulation results. If the model fits, you are good to go. If not, repeat the calibration process.

Utilization

Once you have validated your model, use it to simulate thousands of experiments in minutes.

Common Questions

Mechanistic modeling uses physics-based equations to simulate chromatography experiments. Physical mechanisms such as convection, diffusion, mass transfer, and adsorption are described using first-principles equations. By using mechanistic modeling, the number of real-world experiments can be reduced compared to statistical modeling approaches, while greatly improving process understanding. Learn more about mechanistic modeling.

Mechanistic modeling is based on physical equations that describe the underlying mechanisms within the chromatography column. Statistical models (like DoE) are based on correlations between inputs and outputs and cannot explain the underlying process mechanisms. The advantage of mechanistic models is that they typically require fewer experiments to optimize process parameters, while simultaneously providing a better process understanding. Read about the science behind mechanistic modeling.

With the Efflux modeling platform, anyone can simulate chromatography experiments directly in the browser. We have tailored Efflux for downstream process development, scale-up, screening, root-cause analysis, and tech-transfers. However, Efflux is able to simulate all types of chromatography experiments.

Yes. We understand that your data is sensitive. We use state-of-the-art security systems to keep all of your sensitive data secure. Very sensitive data, like protein sequences, are stored encrypted, meaning that even in the unlikely event of data leakage, your sequences remain secure. Learn more about our security practices.

Yes, we offer contract modeling services. Partner up with us and let our modeling experts handle the modeling for you. That way, you can focus on what you do best and still save time and resources during process development. Learn more about our contract modeling service.
