Linear gradient chromatography
Nettet14. mar. 2024 · A common linear gradient starts with a ratio ¼ of the TLC and ends at 2x the TLC ratio over a distance of 10 column volumes (CV), Figure 5. Figure 5. … NettetIn this study, we propose a new method for increasing the capture chromatography process efficiency, linear flow-velocity gradient (LFG). The method uses a linear decreasing flow-velocity gradient with time during the sample loading. The initial flow velocity, the final flow velocity, and the gradient time are the parameters to be tuned.

Nettet27. sep. 2024 · Some flash chromatography systems such as the Biotage® Isolera, can convert your linear gradient method to a step gradient method by targeting a specific peak or compound in the chromatogram. The system then creates a step gradient to isolate your target with higher purity using less solvent, Figure 2. Figure 2. NettetThe application of the model for the well-characterized protein lysozyme resulted in almost identical model parameters based on either linear salt or pH gradient elution data. For the antibody, only the approach based on linear pH gradients is feasible because of the limited pH range useful for salt gradient elution.
