☁️Application of the Month: Long-term Sampling of Dioxins☁️

Within the European Union, the waste incineration BAT conclusions (WI-BATC) calls for sampling of PCDDs, PCDFs, dioxin-line PCBs, and states maximum concentrations (TEQ weights per volume) obtained either during short-term or long-term sampling. OPSIS offers a system for long-term sampling of dioxins, the DX100.

DOAS stands for Differential Optical Absorption Spectroscopy. The acronym DOAS itself reveals quite a lot of what it is about. “Spectroscopy” is the study of interaction between matter and light, and that is indeed what happens. “Absorption” specifies the optical effect utilized: some wavelengths are absorbed by the molecules. “Optical” tells which wavelengths are in use, and “differential” is the mathematical method applied to the detected spectra, allowing gas concentrations to be calculated. Our monitoring system for marine applications, M800, are one of many OPSIS' products that are based on the method. Learn more about DOAS on our Monitoring Method page on our website https://www.opsis.se/en/knowledge-base/monitoring-methods/the-doas-principle/, or watch our 1-minute-video about our M800 system https://www.youtube.com/watch?v=fMGXCemAWCc&list=PLPh0jmhbCT_FdQKkdu2ZCWbBp-47pfYPw&index=9.

☁️Application of the Month: Marine Monitoring☁️

Many of us who are not in the marine shipping business probably think of vessels as practical means of transportation, or, when it comes to cruising ships, a place to spend your vacation. However, not all of us realize that large ships also are floating large power plants, with all aspects that come with power plants including potential contribution to air pollution.

The environmental aspects of shipping have perhaps mainly been an issue to people living close to major ports, but maritime organizations have for the past decade or so started to address the shipping industry’s impact on air quality.

Marine environments require marine systems. The OPSIS System M800 for shipboard installation is based on the DOAS technology and can be used for emissions monitoring and for monitoring SO2 scrubbers.

Mercury emissions from waste incinerators and other industrial facilities are tightly regulated, creating a need for reliable monitoring of mercury concentrations. Yet measuring the total mercury content of flue gas is not always straightforward. Learn more in our blog post linked below.

Waste incineration might sound negative, but properly managed, it can be an efficient and environmentally sound way to make the best out of waste that cannot easily be recycled. But how can the emissions of air pollutants best be reduced and monitored? Read the blog linked below to find the answer.

The saying “to measure is to know” may sound reasonable. You buy yourself a measurement device, and it shows readings with a lot of digits. All good then? Well, not necessarily. To make the readings comparable with standards and what other devices read, your device needs recurring calibrations.
