OPSIS AB products

A wide range of products are combined into customised systems. Differential Optical Absorption Spectroscopy (DOAS) is the core technology in the OPSIS product portfolio where a combination of light emitters, light receivers, optical fibres, and analysers allows the monitoring of gaseous pollutants and other substances for both emissions monitoring and process control.

LD500 - a good complement to the DOAS analysers. As an alternative to the DOAS systems, OPSIS also offers gas analysis based on laser diode technology, TDL. The TDL technology is a good choice if only a single or a few types of pollutants or other substances are to be monitored, or if a certain measurement performance for a specific type of substance is to be achieved.

Long-term sampling of dioxins, furans, dioxin-like PCBs, and carbon dioxide. Even in very low concentrations, dioxins are some of the world`s most toxic substances. They are formed in combustion processes, especially in waste incineration. Emissions of dioxins from waste-to-energy plants are therefore strictly regulated. However, the concentrations are low and in order to measure them, a sample of the flue gas must first be collected. This is done with a sampler. In the OPSIS version, the same product can also be supplemented with carbon dioxide sampling.

Monitor real emissions from vehicles with internal combustion engines.Emissions from internal combustion engine-driven vehicles create bad air in many parts of the world. Tests against limit values have traditionally been carried out in laboratories and it has been possible for vehicle manufacturers to optimise emissions after the test procedure, with less regard for emissions in real use. To get around this, a standard called `Real Driving Emissions` (RDE) has been introduced, which measures actual emissions.
