The following illustration shows a typical wet dispersion unit installation:
ill 8620

Optical unit (as described in the next section)
Measures the sample using red and blue light wavelengths.
Dispersion unit (in this case the Hydro LV)
Circulates the sample through the cell
Wet cell
Sample flows through the air cell so that it passes through the instrument’s laser
path.
Computer running the Mastersizer application software
Controls both the optical unit and the attached dispersion unit, as well as process-
ing and presenting the measured data.
Other wet dispersion units include the Hydro MV, EV and Hydro SM.
