If a faulty Ozone scrubber is suspected perform the following steps:
Equipment Required
• Reference Ozone Scrubber
• Span Source of 400 ppb Ozone
Procedure
1. Connect a span source (approximately 0.400 ppm O
3
) to the sample port, allow the instrument to
stabilise. Then record the response.

2. Replace the scrubber with a reference Ozone scrubber (refer to Section 6.4.4.1). Allow the
instrument to stabilize and record the response.
3. Compare the two readings. If the second reading exceeds the first by more than 10% the scrubber
should be replaced.
