Why DLS is suitable for your
application
The technique is ideal for the measurement
of the size of colloids, nanoparticles and
molecules, without requiring agitation
to make the sample suitable for analysis.
From the size, an estimate of the molecular
weight can be made, which has the benefit
of being faster to confirm oligomeric state
than size exclusion chromatography (SEC).
