Maintenance And Troubleshooting - Thermo Scientific APEX 100 User Manual

Maintenance and
Troubleshooting
This section describes how to maintain and test your APEX detector, and provides a
troubleshooting guide to help you resolve problems should a fault occur.
Maintenance
You should regularly clean the APEX, if you want it to provide long-term, trouble-free
operation. Please note that certain cleaning agents could affect the integrity and
appearance of the plastics used on the search head. Read the labels on all cleaning
agents to make sure they do not adversely affect polycarbonate- and polyester-plastic
materials. If you have any questions about cleaning procedures, please contact Thermo
Fisher Scientific—as described in the "Contacting Thermo Fisher Scientific" section at the
end of the manual.
Cleaning
Please make sure that your cleaning procedures do not leave residues on the detector's
surfaces, because these might attract dust particles. In addition, please dry all surfaces
after cleaning. In addition, please consult the suppliers of your cleaning agents to make
sure they are suitable for use on conveyors and ancillary equipment, and use the
appropriate dilution levels when cleaning
Do not use high-pressure hoses to clean the APEX as these may damage the APEX or
cause breaches in the integrity of the unit. In addition, using high-pressure cleaning
equipment may compromise safety and lead to problems with contamination.
Checking for Corrosion
Although the APEX is made from corrosion-resistant materials, corrosion may occur. For
example, stainless steel prevents surface corrosion by rapidly producing a strong and
inert oxide layer. Damage to this protective oxide layer may result if you rest iron
objects on the detector's surfaces. Please check for signs of corrosion on a regular basis
and take preventative measures to stop corrosion occurring. Any sign of corrosion
should be investigated. Please report any incidents of corrosion to Thermo Fisher
Scientific.
