The Activated Charcoal Filter Adapter is an accessory that can be installed
or attached to the end of the standard probe or to the end of a telescoping
extension. The filter is typically filled with activated charcoal which acts as
an adsorbent and effectively filters out organic vapors other than methane
or ethane.
A screw cap on the probe end may be removed for refilling the filter with
activated charcoal or other filtering medium.
Applications of the filter include:
Obtaining a clean air sample for zero baseline check and adjustment.
●
Rapid screening of methane and non-methane organic vapors.
●
Selective screening for natural gas surveys.
●
The charcoal filter adapter fits directly into the telescoping wand.
The life of the filter depends on the time in use, the types of compounds,
and concentrations of the compounds being filtered. Under typical
industrial air monitoring conditions, the filter will last for many days of
continuous sampling. For information on replacing the charcoal filter, see
"Replacing the Charcoal Filter" on page 5-14.
