1.5.2 Sample Filter Holder
Refer to Figure 3 for the location of sample filter holder. Within the sample filter holder is a particulate
filter. The particulate filter is a Teflon 5-micron (µm) filter with a diameter of 47 mm. This filter prevents
all particles larger than 5 µm from entering the measurement system that could interfere with sample
measurement.
Note: The 5-micron filter element should be replaced on a regular basis.

1.5.3 CO-CO
2
Converter
Refer to Figure 3 for the location of CO-CO
2
converter. The CO-CO
2
catalytic converter uses platinum
impregnated alumina beads heated to 90 °C as a conversion agent. The catalyst achieves conversion
of 0 - 200 ppm CO to less than 0.1 ppm CO, even in the presence of up to 2% water.
Within the body of the CO-CO
2
converter assembly, there is a heat exchanger used to precondition the
sample gas up to temperature. The sample gas is then drawn into the measurement cell.
