Servomex launches new analyser

Published by

Servomex has launched an analyser that uses pulsed ultraviolet (UV) fluorescence technology to deliver a reliable, continuous measurement of ultra-low sulfur dioxide in emissions and ambient air.

The SERVOPRO SO2 analyser’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 analyser is fitted with a ‘kicker’ to remove them from the sample before analysis, ensuring a reliable, accurate reading.

The analyser can slot into analyser 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.
