One of the challenges of developing a test protocol for dynamic light scattering measurements is getting the concentration of the sample right. Too low, and our scattering measurement fluctuates erratically as we become sensitive to particles entering and leaving the detection volume. Too high, and our assumptions of single scattering break down and the correlation function no longer represents the data we expect.
Here we will discuss how the new Low Volume Disposable Sizing Cell can help in the latter situation, and extend the measurable range of concentrations that can be reliably probed with a side scattering system.
