Measurements.

In Fig. 7.1, 7.2 and 7.3 are shown the results of ONFS measurement. The same samples have been analyzed also by a SALS instrument; the results are shown in the graphs.

**Figure:** ONFS measurement of the $10.0\mathrm{\mu m}$ colloid. A SALS measurement and a theoretical evaluation based on Mie theory are shown.

**Figure:** ONFS measurement of the $5.2\mathrm{\mu m}$ colloid. A SALS measurement and a theoretical evaluation based on Mie theory are shown.

**Figure 7.3:** ONFS measurements of the two colloids. SALS measurements and theoretical evaluations based on Mie theory are shown.

In Fig. 7.4, 7.5 and 7.6 are shown the results of ENFS measurement. The same samples have been analyzed also by a SALS instrument; the result is shown in the graphs.

**Figure:** ENFS measurement of the $10.0\mathrm{\mu m}$ colloid. A SALS measurement and a theoretical evaluation based on Mie theory are shown.

**Figure:** ENFS measurement of the $5.2\mathrm{\mu m}$ colloid. A SALS measurement and a theoretical evaluation based on Mie theory are shown.

**Figure 7.6:** ENFS measurements of the two colloids. SALS measurements and theoretical evaluations based on Mie theory are shown.

Both ONFS and ENFS measurements agree with the SALS measurement, but ONFS gives less accuracy.
