Bibliography

Defines the Standard Reference Method (SRM) for sampling, and determining carbon monoxide content in ducts and stacks emitting to atmosphere. It also explains the Non Dispersive Infra-Red (NDIR) analytical technique, including the sampling system and sample gas conditioning system, to determine CO in flue gases.
