To Replace Sample Compartment Windows - Thermo Scientific Nicolet Summit User Manual

Thermo Scientific
For optimal spectrometer performance, the sample compartment windows must be clear (not
cloudy) and clean (no dust or fingerprints). If your windows become contaminated, the
spectrometer may fail performance and qualification tests. You can order new windows from
us and install them yourself using the instructions below.
NOTICE
• Replace sample compartment windows only with replacement parts supplied by us.
• Do not allow liquids to come into contact with the windows.
• Windows can be scratched and ruined very easily. Do not touch or attempt to clean
them. Dust will not affect the signal, but fingerprints can degrade the performance of
the instrument and permanently damage mirrors or windows. If you wish to remove
dust from a mirror or window, blow it off with a gentle stream of clean, dry air or
nitrogen. (Do not use compressed air from a can; contaminants may cause damage.)
• Leave new windows in their protective packaging until you are ready to insert them in
the spectrometer.
• If you remove working KBr or ZnSe windows from the spectrometer, immediately
place them in the provided protective packaging (includes desiccant) and seal the
package securely.
• KBr windows are clear; ZnSe windows are yellow.
