Notice:
To prevent flow cell failure:
• Do not attempt to disassemble or rebuild the flow cell.
• The pressure through the 2432 Conductivity Detector flow cell must not
exceed 5000 kPa (50 bar, 725 psi). Adjust flow rates accordingly.
• Do not connect any tubing or device that can create backpressure
exceeding the flow cell's maximum pressure rating. In particular, do not
install an optical detector downstream of the 2432 Conductivity Detector.
(You can, however, install a non-optical detector, such as a mass
spectrometer or 2465, downstream of the 2432 Conductivity Detector.)
The actual flow rate range is affected by the combination of solvent viscosity and
backpressure on the flow cell. Increasing the flow rate usually increases the
pressure. High-viscosity fluids generally increase the pressure through the flow cell
and therefore require a lower flow rate. Allowable flow rates are based on the limit of
pressure that each flow cell can withstand. To prevent breakage of a detector flow
cell, total pressure on the flow cell must never exceed the maximum pressure limit.
3.4 Safety and handling
Observe these warning and caution advisories when you perform maintenance
operations on your system.
Warning:
To avoid personal contamination with biohazards or compounds that are
toxic, wear clean, chemical-resistant, powder-free gloves when performing this
procedure.
Warning:
Observe Good Laboratory Practice (GLP) at all times, particularly
when working with hazardous materials. Consult the Material Safety Data
Sheets regarding the solvents you use. Additionally, consult the safety
representative for your organization regarding its protocols for handling such
materials.
Warning:
To avoid electric shock, do not remove protective panels from
system modules. The components within are not user-serviceable.
3.5 Replacing the module's fuses
The module is equipped with fuses that interrupt the electric current when something
within the component fails. They protect both the operator and the equipment. Fuse
failure is, under normal conditions, an extremely rare occurrence. Fuses that
regularly open indicate a probable fault in the component and must be investigated.
