• Sample compartment window check
Visually check that KBr crystal is transparent with using the sample compartment window (STD) made of KBr.
If the KBr crystal has become cloudy, replace it with a new one.
If the KBr crystal has become cloudy, replace it with a new one.
NOTE: The KBr crystal becomes cloudy from absorbing moisture, and therefore reducing transmittance.
If a KBr crystal that has absorbed moisture is not replaced, deliquescence may occur, causing the sample compartment window to become contaminated with KBr solution.

• Replacing the silica gel
When the dehumidifier is running, the humidity inside the interferometer is maintained below 10-plus %. Therefore, the silica gel absorbs moisture at the minimum level.
However, when the sample compartment window (AH) is used, because the window reacts with the corrosive substances in the environment, the transmittance may decrease.
Replace the silica gel, which absorbs the corrosive substances physically, once per three months.
