Dynamic Light Scattering Spectrometer

Zetasizer Helix

Characterize secondary and tertiary structure.
The dynamic light scattering platform is coupled with Raman spectroscopy for protein size and structural determination. Together, these two measurements provide unique insights into colloidal and conformation stability of biopharmaceutical products. The data derived is an effective tool to develop product understanding, necessary in implementing a Quality by Design strategy. Ultimately, the ability to probe the mechanisms, not just the results, of product agglomeration can be used to improve biopharmaceutical formulations.
