Chapter 2
Optical unit (as described in the next section)
Measures the sample using red light detection.
Dry dispersion unit (in this case the Aero S)
Disperses the sample and transports it to the measurement cell.
Dry cell
Sample flows through the air cell so that it passes through the instrument's laser
path.
Vacuum unit
Removes the sample from the cell exhaust once it has been measured.
Ancillary switching unit
An external control accessory that is used to switch on the vacuum unit required
for the sample extraction during each measurement.
Computer running the Mastersizer application software (not shown)
Controls both the optical unit and the attached dispersion unit, as well as process-
ing and presenting the measured data.
