Foam Filters
The gray foam filters used inside the absorber columns become worn over time and should be inspected
regularly and replaced when torn or reduced in size. The foam must be of an open celled type, such as
packing foam. The foam filters at the bottom of each column will likely require more frequent changes
versus the upper foam filters.

Absorber Filters
Each absorber end cap contains a white plastic filter disk. Generally these do not need to be replaced but
should be checked periodically. However, they must be present to prevent any of the column contents
being drawn with the gas stream causing damage to the instrument.
“O” Rings
All “O” Rings on the absorber columns should periodically (every couple of weeks) receive a slight smear
of silicone grease to aid ease of fitting, improve the seal and extend the life of the “O” rings and to keep
them from cracking or breaking. Once sealed, end fittings should be checked to ensure that the O-rings
are seated correctly in their groove and that they are not trapped or pinched resulting in system leaks.

Access to Internal Components
Under most circumstances there should be no need to service internal components (pump, IRGA, IR
source, etc.). There are only two internal items that may require replacement at some point:
•
Internal, rechargeable Li-ion battery pack
•
In-line hydrophobic filters (3)
In the event that you do need to troubleshoot and examine these items you can gain access into the
TARGAS-1 enclosure by removing the 8 screws securing the base to the main enclosure as shown
below.
