Servomex provides solution for accurate monitoring of sulfur dioxide

As part of its comprehensive emissions monitoring analyzer range, Servomex, the world leader in gas analysis, offers the SERVOPRO SO2, an analyzer that uses pulsed Ultraviolet (UV) Fluorescence technology to deliver a reliable, continuous measurement of ultra-low sulfur dioxide in emissions and ambient air.

The analyzer’s measurement is based upon UV radiation of the sulfur dioxide molecule using light in the range of 190-230 nm. The molecule absorbs the light into an excited state and then decays back down to the ground state, where a photomultiplier tube (PMT) converts the signal into SO2 concentration.

To prevent interference and quenching from polycyclic aromatic hydrocarbons (PAHs) such as naphthalene, the SERVOPRO SO2 is fitted with a “kicker” to remove them from the sample before analysis, ensuring a reliable, accurate reading.

The analyzer is designed to slot seamlessly into analyzer racks, making it easy to integrate with existing emissions monitoring systems, and offers comprehensive data logging and remote viewing of more than 200 operational parameters.

The operational status of the analyzer can be seen at a glance thanks to an instant-response lighting system.

Barbara Marshik, Servomex’s Market Segment Manager – Power, said: “The SERVOPRO SO2 is designed for ultra-low SO2 emissions monitoring, delivering superior performance for a low cost of ownership. It uses proven technology to deliver a continuous measurement you can rely on.”

The SERVOPRO SO2 is part of Servomex’s emissions monitoring analyzer range set to meet the lower regulatory requirements, joining the SERVOPRO NOx, which uses Chemiluminescence Detection, the heated-oven, Flame Ionization Detection-based HFID, and the SERVOPRO 4900 multi-gas analyzer to offer a comprehensive solution for the monitoring of NO, NO2, NOx, O2, SO2, methane, total hydrocarbons, and non-methane hydrocarbons in a diverse range of industrial and vehicle applications.
