Procedure for automatic detection for the saturation of a
molecular filter using acetone
Acetone evaporates easily and quickly at room temperature and can be used as a tracer to check mocular filters saturation.
Following procedure provides three methods to determine activated carbon filters saturation, evaporating a small amount of
acetone withing the Captair Smart fume hood and using either a colorimetric tube for acetone, Molecode S saturation sensor
or a PID device. The result of the test will indicate weither it is necessary to replace filter or not.
Required material:
•
5 mL of acetone (not provided)
•
Absorbing cloth (not provided)
•
Cup or crucible (not provided)
•
Hose (provided)
•
Sampling pump (not provided)
•
Colorimetric tube (not provided)
Remove protection covers
Turn on the unit and start the air flow
