(FTIR) Replacement of Silica Gels - IRPrestage-21

NOTE: Though the dry unit is built in the IRPrestige-21, silica gel is used also to cope with failure of the dry unit and power interruption.

 

1. Remove the top cover by lifting it from the right side.

  

2. When the top cover is removed, the interferometer case cover can be seen. The lid on the right side (1) is provided for replacing the beam splitter. Remove the four screws which fix this lid (2), then open the lid.
3. When the lid for replacing the beam splitter is opened, the silica gel case (2) and the beam splitter installation position (3) can be seen.

  

4. Pull the silica gel case upward to remove it, replace the entire silica gel inside it with a new one, then install it again.
