(C) Sampling Using One Passive Gas Tube (for Organic Solvents) and One DNPH
Passive Gas Tube (Total of Two)
(1)
Install an activated carbon passive gas tube positioning stopper on one end of the
passive gas tube (for organic solvents) .
(2)
Remove the plugs from both ends of the DNPH passive gas tube and install plugs A
and B included with the semi-active sampler for installing DNPH passive gas tubes.
•
Keep the plugs originally installed in the DNPH passive gas tube stored until
sampling is finished. When sampling is finished, reinstall the original plugs.
(3)
Insert the end of the passive gas tube that does not have the stopper attached into
the hole in mounting plug B that is installed in one end of the DNPH passive gas
tube.
(4)
Install mounting plug A of the DNPH passive gas tube into the threaded portion of
the intake port cap.
(5)
Install the extension into the main semi-active sampler unit, if not already installed.
(6)
Install the intake port cap onto the extension of the semi-active sampler.
(7)
Holding the battery case, remove the battery cap and insert a new AA alkaline
battery* into the case, with the negative (-) terminal oriented toward the battery cap.
(8)
When the battery cap is screwed all the way on, the fan motor begins to rotate and
the sampler will begin sampling. (The fan motor may not rotate or may stop rotating
if the battery cap is not tightened properly.)
* Be sure to install a new AA alkaline battery. Installing a partially used battery or
another type of battery may prevent the sampler from operating for an adequately
long period. It may also prevent operating (coordinating) fan motor and LED functions
properly.
