Introduction; Replacing The Sample Tubing - Malvern Mastersizer Series Getting Started

Introduction

The Mastersizer has been designed so that supervisor/operator maintenance is
kept to a minimum. It should be fully understood that no one, except a qualified
Malvern representative, should remove the transmitter or receiver covers of the
instrument. The supervisor should only remove the sample area cover if spray
measurements are to be performed and should only do so after reading the Health
and Safety manual and the instruction manual for the spray accessories.

Warning!
Failure to follow these guidelines correctly could result in the emission of laser
radiation. Laser radiation can be harmful to the body and can cause permanent
eye damage.
This section explains the routine maintenance procedures that the supervisor can
perform. These procedures are:
. Replacing the sample tubes to and from the flow cell.
. Replacing the fuses.
. Cleaning and replacing the cell windows and window "O" rings.
. Cleaning the range lenses and beam expander.
. Cleaning the covers.
An operator may perform all the above procedures

Replacing the sample tubing

If organic solvents are regularly used as a dispersant you may find that the plastic
tubing that connects the flow cell becomes hard and discoloured. To change the
tubing simply pull it off the connecting pipes and replace with new tubing.
