Abstract Information :
With a range of products and technologies available in the continuous gas analyzer space, it can be a challenge to know which product is the right fit for a particular CEMs measurement. CGAs can employ a range of traditional technologies including non-dispersive infrared (NDIR) and ultraviolet (NDUV), thermal conductivity detectors (TCD), electrochemical methods (EC), and trace and paramagnetic O2 detectors. Over the past decade laser-based measurements have become more prevalent and accepted in industry, using both near-IR tunable diode lasers (TDLs) and more recently mid-IR quantum cascade lasers (QCLs). With a range of technologies in the marketplace it is not always clear what type of product will best meet the measurement requirements for a particular installation, with factors such as price, maintenance and measurement accuracy to consider. In this presentation we will discuss the technologies available, pros and cons of measuring by different techniques, and provide some examples of successful CEMs installations utilizing different technologies.
