Discover the OPSIS podcast on industrial gas monitoring! We dive into how production processes can be controlled, what is emitted from industrial stacks, , what is really going on in the air around industries, and much more. We talk about why gas monitoring matters and how to measure gas concentrations.
Whether you are an environmental engineer, an instrument technician, or just curious about how our industries manages emissions monitoring and process control – welcome to listen.

#10: Inside the Gas Analyser – the Tuneable Diode Laser
OPSIS is probably best known for its gas analyser systems based on broad-band (“white”) light from xenon lamps and spectrometers or interferometers as the core analysis devices. However, OPSIS also offers an instrument type base on a quite different optical technique – light absorption detected by utilizing a tuneable diode laser. Let’s take a closer look!

#09: Cemented Success
Cement is a versatile building material, but it comes with environmental issues, not only from a greenhouse gas perspective (carbon dioxide emissions) but also related to the production process where high levels of other pollutants may be emitted. Emissions control and monitoring are often required but there are challenges. In this blog post, we discuss how cement is produced and what the environmental challenges are, and how they can be managed using OPSIS monitoring systems. The prese...

#08: Inside the Gas Analyser – the Interferometer
Some OPSIS gas analysers are based on a device called an interferometer. Like a spectrometer, it separates light into its wavelength components, but it’s done in a special and indirect way. Keep on reading to find out how! The presentation is based on facts from the OPSIS blog on this topic. Dialogue and voices are AI generated.

#07: Regulating Mercury Emissions
Have you heard of new and strict regulations on mercury emissions within the European Union? If you are responsible for the operations at a waste incineration facility, you probably have. But what’s the issue with mercury, and what do the EU regulations say? The presentation is based on facts from the OPSIS blog on this topic. Dialogue and voices are AI generated.

#06: Inside the Gas Analyser – the Spectrometer
Several of OPSIS gas analyser types are based on a device called a spectrometer. It separates light into its wavelength components, allowing the analyser to detect light absorption and thereby determine gas concentrations. Let’s take a closer look at how a spectrometer works!

#05: Continuous Emissions Monitoring of Total Mercury
Mercury emissions from waste incinerators and other industrial facilities are often strictly regulated. This calls for monitoring of mercury concentrations. That is not always an easy task, but there is a method available giving the true total mercury content in the flue gas. Let us take a closer look at the topic The presentation is based on facts from the OPSIS blog on this topic. Dialogue and voices are AI generated.

#01 Pollutants in Emissions to Air – What’s in the Smoke?
Back in the nineteenth century or so, industries pouring out smoke through the stacks were considered signs of progress and prosperity. However, that changed when the effects of the emissions became apparent, including smog, acid rain, and respiratory diseases. Nowadays, the smoke is usually much cleaner thanks to more efficient production processes and flue gas treatment, but there’s still smoke. What’s in it? The presentation is based on facts from the OPSIS blog on this topic. Dialogue an...
