Final answer:
Handle the salt plate in IR spectroscopy with forceps or gloves, clean it after use with compatible solvents, and store it in a desiccator to prevent damage and moisture absorption.
Step-by-step explanation:
To care for a salt plate in IR spectroscopy, it's important to handle the salt plate with care, as they are quite fragile and can easily be damaged by moisture or oils from the skin. Always use gloves or forceps, which should be sterilized in alcohol if necessary, to handle the plate. After each use, the salt plate should be cleaned to remove any residue, typically using solvents compatible with the salt material and then dried with a gentle stream of air. It's also crucial to store the salt plate in a desiccator to prevent moisture absorption which can cause damage. Avoid contact with hard objects to prevent scratching the surface, and ensure that the plate is stored in a safe, stable location to prevent accidental dropping.
