IRAffinity-1
Chapter 5 Maintenance and Inspection
The following inspections are necessary to keep your FTIR condition. There are two types of inspection.
5.1.1 Start-Up Inspection
Start-up inspection is an inspection before use your FTIR.
• Dry indicator check This check must be done before turning ON.
• Silica gel check This check must be done before turning ON.
• Power spectrum check
5.1.1.1 Dry Indicator Check
There are two indicators - an orange lamp as Dry indicator and a green lamp as Power indicator on
the front. Dry indicator lights show the humidity in the interferometer of the FTIR even if the FTIR
power is Off. Confirm that the Dry indicator is on.
If the Dry indicator does not light, check the connection of a power cord between FTIR and AC
supply, and that the AC supply works normally. If above two check points are correct, the humidity
in the interferometer is high and the optical elements might be damaged.
In this case;
1. Disconnect the power cord immediately and do not use your IRAffinity-1.
2. Remove the Top cover and replace the silica gel packages.
3. Please contact your SHIMADZU representative.
Start-up inspection Is an inspection before use your FTIR.
• Dry indicator check
• Silica gel check
• Power spectrum check
Periodic inspection Is an inspection to be done once a week even if your FTIR is not operated.
• Dry indicator check
• Silica gel check
WARNING
The Start-up inspection and the Periodic inspection must be done!
The Start-up inspection and the Periodic inspection must be done. If these checks are not done and Silica
gel has been degraded for long time, the KBr beam splitter deliquesces and performance of the FTIR
becomes low. In worst case, FTIR does not work. In such case, a SHIMADZU service engineer must replace
the beam splitter and align the FTIR condition. Repairing costs are high.
NOTE
This check must be done before turning ON.
NOTE
IRAffinity-1 includes a Dry unit to desiccate the interferometer and a Humidity sensor to monitor
the humidity. Never cut the AC power to the IRAffinity-1, because these functions run on AC
power.
