In this session, we will step back and look at the full picture of a Continuous Emissions Monitoring system, using the analysers you have just learned about as our starting point. The QCL Cascade and the XStream provide the gas measurements, but they are only one part of a much larger ecosystem. A CEM system is a combination of equipment that works together to pull a sample from the process, condition it, measure it, and deliver dependable information to the plant. Our goal is to show how all these pieces connect and why the analyser depends on a well designed supporting structure in order to perform reliably.
We will focus on the flow of the system rather than the internal details. A CEM system begins with the extraction equipment on the stack or duct, continues through heated lines and sample conditioning hardware, and finally reaches the analysers. Once the measurements are taken, the information moves into the plant’s control and data systems. Each stage has a simple purpose: protect the analyser, preserve the integrity of the gas sample, and maintain consistent operation. When everything works together, the system delivers stable, meaningful readings that technicians can trust every day, even in northern Ontario winters.
Finally, we will highlight how Lakeside supports this entire lifecycle. Lakeside designs complete CEM packages tailored to each site, builds them in‑house, installs them on location, and provides ongoing support to keep them running year after year. Whether it is troubleshooting sample flow issues, replacing components, helping with start‑up, or simply answering questions, we stay involved from concept to maintenance. By the end of this presentation, you will have a clear understanding of how the analysers you have learned about fit into the larger CEM system, and how Lakeside ensures that the entire system works as a cohesive, dependable solution.
