Cleaning the instrument
Laser scattering is a high resolution optical method in which the detectors and
windows are an integral part of the measurement zone. Dust or smears on
windows scatter light that is measured with the spray scattering. The process of
measuring both a background and a spray and then subtracting the background
does correct for such contributions. However, this correction is first order only
and excessive dirt on the optics will degrade the instrument’s sensitivity.
We recommend cleaning the instrument after each set of measurements.

Warning!
Thoroughly clean all the following:
.
The covers – periodically, using a mild soap solution and silicon cloth. The
paint has a solvent resistant finish, but it is good practice never to use a sol-
vent based solution as this may result in damage to the painted surfaces.
.
The windows – using a suitable anti-static spray or mild soap solution.
Guidelines
.
Always ensure the instrument is completely dry before applying power.
.
If using alcohol to remove grease or fingerprints, be careful when handling
it. It is flammable so keep away it from power switches, etc.
.
Never use an abrasive cleaner to clean the instrument as this may result in
damage to the painted surfaces.

Always ensure that the instrument is disconnected from the power
supply and all electrical cables are disconnected.
