1.5.1 Particulate filter
The Particulate filter is a Teflon 5 micron (µm) filter with a diameter
of 47mm. This filter eliminates all particles larger than 5µm and
condensed water vapour that interfere with sample measurement.
1.5.2 Hydrocarbon Kicker
The Hydrocarbon kicker removes interfering hydrocarbons from
sample air. This is achieved by using counter current exchange, where
an air with a lower concentration moves in an opposite direction to air
with a higher concentration. The high concentration of hydrocarbons
diffuse through a selective permeation membrane to the low
concentration air and are removed with exhaust air. Increasing the flow
of the low concentration air also increase the rate of diffusion.
1.5.3 Zero Air Scrubber
A charcoal scrubber is used to produce SO
2
free air which is used in
the hydrocarbon kicker to remove hydrocarbons from sample air.
