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!

In the traditional approach to air quality monitoring, those “who wants to know” have also owned and maintained the monitoring equipment generating the answers. However, recent years’ slimmed organizations have opened up for an alternative: to buy air quality data instead of hardware. What are the pros and cons of the two approaches?

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!

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!

A new European Union directive on air quality has been in the pipe for some years and now it seems to be only formalities left for it to become effective. The intention with the directive is to further reduce air pollution in the EU and to achieve the EU’s zero air pollution vision by 2050.

Air quality is essential to all of us, and consequently, so is the monitoring of air quality. However, what should be monitored, and where, and how? There are many bids on that. For example, the European Union has set minimum requirements on the surveillance of the air we breathe. Let’s have a closer look!

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?
