Renewing the disposable desiccant
CAUTION
Old, used desiccant releases moisture and can cause catastrophic
failure of KBr optics.
Do not use damaged packs of desiccant. Make sure that the packs
you use have not been left in contact with the air.
You can purchase disposable desiccant kits from PerkinElmer (Part Number N017 1159).
A kit contains two packs of desiccant, and three kits are required.
1. Inspect the humidity indicator card in the plastic bags in which the spare desiccant
packs are packed. If the card indicates humidity in the bag, discard the desiccant
pack.
2. Remove the sample area cover, if fitted, by opening the cover, pressing the clip and
pulling the cover vertically to remove.
