Inter laboratory comparisons for sulphur dioxide in nitrogen for ambient air and stack gas emission monitoring

摘要

1. NMISA - Gas metrology as part of Gas Analysis Working Group (GAWG) has a mandate to provide measurement traceability to the air pollution monitoring industry. 2. Environmental assets and natural resources that are well protected and continually enhanced (Monitoring Gases); 3. Designed to test the capabilities of the participants to measure the sulphur dioxide concentration levels at ambient and stack emission level. This will give evidence of the calibration and measurement capability of the participant laboratory for SO_2. 4. Strive to create a cleaner environment for all South Africans and contribute to a better and safer Africa and world.
