Gas Mixtures for Stack Emissions Monitoring Keeping It Simple

The stack emissions monitoring market has undergone substantial legislative and quality changes over the past several years and this has resulted in ever increasing pressures on organizations and individuals to deliver products and services to a higher level of acceptance. There is no hiding from the fact that documented guidance and information can be misinterpreted and this has been evident due to the different approaches that have been put into practice. To further complicate matters the demands on OEM’s, Test Houses and Process  perators are quite different, so what meets the requirements of one, is not suitable for the other and this in itself has caused some confusion, and resulted in incorrect selection of gases.

Looking specifically at gas mixtures, examples of common terminology frequently used are: Traceability, Accredited Gases & Non Accredited Gases and Uncertainty. But these terms in turn raise a host of frequently asked questions.

Traceability - What is traceability? What is the interpretation of (Inter)National Standards? Are you using traceable gases to comply with your standard? When do you need to use traceable gases? Accredited & Non Accredited – UKAS Accredited? ISO17025 Accredited? ILAC and Mutual Recognition? Uncertainty - What does the Certificate data actually mean? Are you using the lowest uncertainties available? Are you confident that you fully understand these terms and they are being applied correctly in your business? Choosing the correct gas mixture
