Preparation and Assembly
Handling
Wear powder-free gloves when handling cassett es and use forceps when working
with fi lters and foams to prevent the transfer of moisture, dust, or other contami-
nants onto the sampling media. Users may wish to use sterile gloves and forceps
depending on the contaminant of interest.
Cleaning the Sampler
1. Disassemble the IOM Sampler (Figures 1, 2, and 3).
2. Place parts in an ultrasonic cleaner with water and a wett ing agent such as a mild
soap. IOM components may also be cleaned with a solvent such as isopropyl
alcohol. O-rings should be cleaned separately using water only.

not use solvents on O-rings.
When using solvents, protect against splashes to the eye, vapor
inhalation, and vapor ignition.
3. Clean the components using a clean lint-free paper, cloth, or soft brush. Allow
components to dry completely.
