The optical unit
The Zetasizer optics unit can be divided into three areas for the purposes of this description. These are; the front panel (1), the sample area (2) and the rear panel (3 ) . Each of these are discussed below.
Front panel
Two LEDs are situated on the front panel (1). The far left LED glows orange to indicate that power is on. The right hand LED will glow green shortly after the instrument is switched on to indicate that the instrument is ready to make a measurement, it will flash red when a measurement is being made.
Sample area
The illustration below identifies the features of the sample area.
(1) Hinged sample compartment cover
To access the sample compartment the cover must be raised. There is a mechanical laser interlock connected to the cover and an electrical interlock to cut off the power supply to the cell. Consequently, laser radiation is inaccessible as soon as the cover is opened. When the cover is lowered completely the laser will illuminate the sample.
(2) Pinhole
Dependent on the system ordered, systems incorporating size measurement (i.e. Zetasizer 1000 and 3000 series) are supplied with a 200 micron pinhole fitted. This should not be changed in normal operation.
(3) Sample valves
The sample valves control the flow of sample through the cell.
(4) Size cell
The sizing cell is used to make size measurements. This is only applicable to the Zetasizer 1000 and 3000 series systems. The cell is fitted with a thermal cover.
Plastic or quartz cuvettes can be used. The type chosen will be dictated by chemical compatibility with the sample and dispersant. It is strongly recommended that tops are fitted to the sample cuvette prior to insertion into the cell holder. This is to prevent spillage into the sample holder and better thermal stability. In the event of a large spillage a service visit by a Malvern representative is recommended.
For measurements done above ambient temperature it is recommended that the insulating thermal cover is fitted.
(5) Zeta potential capillary cell
The capillary cell is used to make zeta potential measurements.
(6) Electrode connectors
These electrodes are connected to the electrode blocks once the capillary is fitted. The grey electrode wires are colour coded. The yellow connector is clipped to the yellow electrode at the rear of the cell and obviously the red connector on the red coded electrode. Connectors are a simple push fit, however to remove them, the clip should be pushed sideways rather that pulled.
(7) Sample in/out connectors
The sample in/out connectors are used to inject the sample into the capillary and sizing flowcell.
(8) Aqueous / non Aqueous dip cell readback connector
The readback lead from the Aqueous / non Aqueous Cells is connected to this connector.
Rear panel
Use the diagram below to identify the features on the rear panel and their function.
(1) On/off switch
This is the main power switch for the instrument.
(2) Main fuse holder
The main instrument fuse (only to be replaced by the supervisor or a Malvern representative).
(3) Mains power socket
The mains power supply is connected to here.
(4) Detector output test connector (Service personnel only)
This connector is only used by Malvern Service personnel for testing the detector output. The user should never use this connector.
(5) Computer COM1 connector
This connector is connected to the computer RS232, COM1, I0I0 or Serial port (depending on computer).
(6) External link (Service personnel only)
This connector is only used by Malvern Service personnel. The user should never use this connector.
(7) Aux. output
This port is used to connect the MPT1 Autotitrator Accessory to the instrument. Details of the connections will be found in the relevant Accessory manual.
(8) Auxiliary fuses
Fuses for Accessory options. Details of these fuses will be found in the relevant Accessory manual.
