Maintenance . 67
Daily Checks
The instrument is constructed with high-quality components and requires little maintenance other
than to keep it clean and free of dust.
To protect the optical system from dust and fumes, you should keep the sample compartment
cover closed except for when you are carrying out work in the compartment. The sample
compartment windows should always be installed.
You should observe the following care routine to maintain your instrument in good condition:
• Clean all spilled materials from the affected area immediately and wipe it dry with lint-free
paper or cloth.
If you have to wipe the sample compartment windows, make sure you do not introduce
scratches. The windows are optical components, and you should handle them in the same way
as high-quality cells.
• Do not leave samples, particularly those given to fuming or evaporation, in the sample
compartment for longer than necessary.
•
If any type of sample handling system is installed and portions of it are left in the sample
compartment (such as a sipper and flow cell), make certain that the system is cleaned at the
end of the working day.
Generally, such systems should be filled with deionized water when left overnight.
CAUTION
Spills
Take care not to spill liquids onto the spectrometer.
Expensive damage can result to the optics or electronics if liquids are
spilled and run inside the instrument.
Cleaning the Instrument Covers
You can clean the outside of the instrument using a damp cloth. Mild detergent may be used, if
necessary. Always perform a patch test on an inconspicuous area of the instrument before you
clean the entire instrument.
Cleaning the Sample Compartment
You must clean the sample compartment every time anything is spilled into it. This preserves the
matt-black finish, and prevents corrosion and contamination.
The standard sample compartment baseplates have drain holes in them, as shown in Figure 30, to
allow spilt liquids to run-off to the benchtop underneath the instrument. If required, place a sheet
of thick filter paper under the instrument.
