ABSTRACT
Dynamic light scattering is at present the most frequently used
characterization technique to receive information on the size
of macromolecules or supramolecular structures and compact
colloidal particles. With the instruments available on the market,
measurements are quickly performed with agreeable reproducibil-
ity. The instruments are equippedwith powerful softwares such that
only a few manipulations are needed to obtain the desired results.
Easy handling of the instruments gives a safe feeling of reliability.
However, the easiness and high reproducibility of measurements is
deceptive and can become very misleading if one relies too much
on the computer and is not keeping a skeptical mind in relation
to physical expectations. Mostly the software of the instruments is
based on two significant conditions:
