CEMS Analyzers play a vital role in regulatory compliance for your facilities. With constant technological advancements and evolving regulatory requirements, older CEMS analyzers can become obsolete, posing risks to both compliance and operational efficiency. The following information serves as a walkthrough of how to identify if your CEMS analyzers are obsolete, why you should upgrade yours, and how ESC Spectrum can help.
How You Can Check if Your Analyzer is Obsolete
The first step to checking if your CEMS Analyzer is obsolete is identifying the supplier company and checking their website for a list of products that are no longer supported. ESC Spectrum works with a variety of analyzer suppliers and is always working to inform customers when products become obsolete. The following are some common analyzers from our suppliers that no longer receive full support or maintenance services from suppliers.

Why You Should Upgrade Your Analyzer Sooner Rather Than Later
If your analyzer is obsolete, you are risking your CEMS not having the capability to measure emissions properly to comply with regulations. This can be caused by inaccurate data, limited monitoring capabilities, maintenance challenges, or data that is incompatible with modern DAS technology and reporting requirements. With an outdated analyzer, these issues are more difficult to mitigate due to discontinued support and maintenance.
Here are a few benefits of upgrading to a newer version:
- Compliance Assurance: Investing in a more up-to-date analyzer can provide you with more accurate emissions requirements, increasing ease of meeting regulatory requirements.
- Enhanced Monitoring Capabilities: Updated analyzers come with more advanced features such as real-time monitoring, improved sensitivity, or a wider range of measurable pollutants.
- Operational Efficiency: Modern analyzers also require less maintenance, which can reduce downtime and added costs for your facilities.
- Up-To-Date Digital Solutions: The newer your analyzer, the more compatible it may be with current data acquisition and reporting software.
Additional Steps to Maintain Your Analyzers
Even if your analyzer is still being supported, it is important to ensure that it receives regular maintenance to avoid issues with downtime and reliability.
