5.6. Scrubbers and Expendables

5.6.1. Charcoal Scrubber (Option 64A)

This kit includes a charcoal scrubber cartridge, which is used to remove NO
exhaust port. Applications include, but are not limited to, the removal of NO
pump exhaust if that exhaust cannot be vented outside the analyzer shelter or if the vent
line is not far enough away from the analyzer inlet port (in which case the exhaust would be
measured again by the analyzer). The kit does not include any mounting clips, filters or
tubing. To order a refill for this cartridge, specify the refill kit listed below.
Older models of the nitrogen oxides analyzer used this type of charcoal scrubber to remove
both NO and excess ozone from the exhaust. However, we do not recommend this
2
particular application because of the potentially explosive nature of the mixture.

5.6.2. Charcoal Refill Kit (Part# 00596)

This refill kit contains two plastic bottles with a total of 2.5 kg (5.5 pounds) charcoal, which
lasts for about five refills of Option 64A.

5.6.3. Zero Air Scrubber (Option 64B)

This kit includes a zero air scrubber cartridge, which can be used to produce and supply
zero air to the analyzer's ZERO inlet port. The cartridge mounts to the outside rear panel by
means of two rubberized clips and contains two chemicals, 50% volume of Purafil Chemi-
sorbant to convert NO to NO
The zero air scrubber exit contains a particle filter that retains any dust coming from the
cartridge and connects with a 0.25" PVC tubing to the ZERO inlet port. The chemicals need
to be exchanged periodically (use Option 43) to prevent saturation and break-through of
NO into the zero air stream. This kit is recommended if no other zero air source is available
X
and if the analyzer is equipped with the zero/span valve option (Section 5.5.1). The kit is
included in the IZS option but not in the zero/span valve option.

5.6.4. Zero Air Scrubber Maintenance Kit (Option 43)

This kit includes the items needed to refurbish the external zero air scrubber.
