Duration: 37 minutes 13 secondsWhilst being able to measure particles of below 1 nm size, DLS is preferentially sensitive to larger particles due to the 6th power relationship between particle radius and scattering intensity. This means that sample preparation typically needs to be scrupulous, especially for low scattering samples such as proteins and biological molecules. The contribution to contaminants such as dust and aggregates can be mitigated by filtering, however this may not always be practical and constitutes a financial burden, both in terms of additional sample preparation time and consumables costs. In this webinar we introduce a new DLS data capture process called Adaptive Correlation which addresses these issues to provide a more complete and accurate characterization of your sample.
