Thermo Scientific 9800 QC Laser-Based SO3 Analyzer Datasheet

The Thermo Scientific 9800 QC Laser-based SO₃ Analyzer uses advanced Quantum Cascade (QC) laser spectroscopy to provide high sensitivity, optimal selectivity, and continuous direct measurement of sulfur trioxide (SO₃) within the industrial plant process. The 9800 SO₃ analyzer is a primary component of the Thermo Scientific Arke SO₃ System.

The QC laser is coupled with a low-frequency sweep ramp and focused into a high-temperature optical cell. The frequency is then filtered through a cooled photo voltaic detector. The reduction of absorption line broadening by the QC laser provides optimal selectivity as the spectral features of water or Sulfur Dioxide (SO₂) are limited from overlapping with the SO₃ features. The spectral feature separation can allow the analyzer to measure SO₂, an important attribute in determination of the SO₃ generator efficiency.

The 9800 SO₃ analyzer features an advanced software platform with an intuitive touch-screen interface and is easily integrated into existing plant process controls using common communication protocols.
