Trace gas analyser

Trace gas analysis is a crucial process in various industries, where the ability to accurately measure specific compounds in low concentrations is essential. ETG Risorse e Tecnologia has developed an innovative solution for this purpose with their ETG 8900 QEPAS series. These analyzers utilize Quartz Enhanced PhotoAcoustic Spectroscopy (QEPAS) technology, which has seen significant advancements in recent years.

The photoacoustic effect, discovered by Alexander Graham Bell in 1880, involves the absorption of light energy by gas molecules, resulting in vibrations that generate sound waves. By measuring the intensity of these sound waves, and selectively exciting only the desired molecules, a highly selective and indirect measurement of gas concentration can be obtained, eliminating interference from other compounds. This makes QEPAS technology ideal for detecting a limited number of compounds in very low concentrations.

ETG Risorse e Tecnologia has leveraged their decades of experience in the industry to create a simple, reliable, and robust system for trace gas analysis. The ETG 8900 QEPAS series is available in both rack and portable configurations, and can be customized based on the application’s specific requirements. This includes the configuration, detection limits, and ranges, all of which can be tailored to meet the customer’s needs.

The QEPAS analyzers offered by ETG Risorse e Tecnologia are perfect for measuring a limited number of compounds, since lasers can only operate in very narrow frequency ranges. With our expertise, we can perform personalized simulations to choose the appropriate frequencies to obtain a clean and interference-free signal from the desired compound.

In conclusion, the ETG 8900 QEPAS series offers an effective and efficient solution for trace gas analysis. With their personalized simulations and expertise, ETG Risorse e Tecnologia can create a customized system that meets specific requirements. Whether it’s for compliance monitoring or research and development, the ETG 8900 QEPAS series is an excellent choice for accurate and reliable trace gas analysis.
