3.3.2.7. TS and Zero Air Scrubbers
There are two charcoal scrubbers in the analyzer chassis of the 6200T. The scrubber
canister on the outside of the rear panel of the analyzer is a standard charcoal scrubber
that supplies zero air for the diluter assembly. The second scrubber is located inside the
analyzer behind the sample filter. This scrubber uses a specially impregnated charcoal
(TAI Part# CH_52) which is especially effective in scrubbing TS gasses. This filter is
used to scrub TS from the inlet sample gas for use in zero calibrating the analyzer.
3.3.2.8. Pneumatic Layout with O

Sensor Option
Figure 3-21 shows the internal, pneumatic connections for the analyzer with the oxygen
(O

) sensor option installed. Pneumatically, the O
2
sensor draws a flow of 80 cm³/min in
addition to the normal sample flow rate. It is separately controlled with its own critical
flow orifice.
