New H2S Analyser Uses Laser Technology for Precise Measurements in Real-time

SpectraSensors’ (USA) gas analysers employ patented "tunable diode laser" (TDL) technology for dependable and precise results. The wavelength of IR energy is adjusted by varying the current through the laser. The result is approximately 1000 times increased resolution than an optical photometer, negating the effect of overlapping wavelengths of background components in many applications.

SpectraSensors analysers have a lower initial cost and do not require the support gases and maintenance of a chromatograph or traditional H2O or H2S analysers. Cost of ownership over a five year period is a fraction of the other methods because there is no need for highly trained technicians and factory set calibrations last the life of the analyser. TDL technology allows for smaller foot print, simple installation and continuous real-time measurements that enable enhanced process control.
