Optimal Spectroscopy Configurations for DOAS

Dive into the world of emission monitoring

While carbon emissions from fossil fuels dominate headlines, pollutants like sulfur oxides (SOx) and nitrogen oxides (NOx) significantly impact air quality and human health. In a previous application note on Differential Optical Absorption Spectroscopy (DOAS), we explored its role in Continuous Emission Monitoring Systems (CEMS). Now, we invite you to delve deeper into the technique from a fresh perspective, focusing on optimal spectrometer configurations.

In this document, we revisit the basics of DOAS, providing insights into its differential absorption spectroscopy methodology and showcasing a typical DOAS-CEMS system configuration. As governments advocate for stricter emissions standards and industries invest in a greener future, the demand for field-deployable CEMS based on DOAS is on the rise. Avantes’ unique spectrometer offerings, highlighted in this application note, position us as leaders in providing sensitivity, stability, resolution, and stray light rejection essential for DOAS applications.
