(Model T100) uses the proven UV fluorescence principle, coupled with a state of the art user interface to provide . Ultraviolet Fluorescence Detection (UVD): UVD involves the excitation of sulfur compounds by ultraviolet light. When sulfur-containing compounds are combusted, they produce sulfur dioxide (SO2), which emits characteristic fluorescence when excited by UV light. The emitted fluorescence is measured to determine the sulfur concentration.
The Model T100 uses the proven UV fluorescence principle, coupled with a state of the art user interface to provide easy, accurate, and dependable measurements of low level SO 2. Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift and a reference detector to correct for changes in UV lamp intensity.Applied to SO2 measurement, the universally known UV fluorescent principle consists in detecting the characteristic fluorescence radiation emitted by SO2 molecules. In the presence of a specific wavelength of UV light (214 nm) the SO2 molecules reach a temporary excited electronic state.H2S / SO2 UV Fluorescence Analyzer. The model 6400T uses a proven UV fluorescence principle coupled with state-of-the-art Microprocessor technology to provide accurate and dependable measurements of low level SO2. The 6400T-H2S measures hydrogen sulfide (H2S) by incorporating a catalytic converter set at 600°F (315°C) to oxidize H2S into SO2 .
It operates on the principle that SO2 molecules absorb ultraviolet (UV) light and become excited at one wavelength, then decays to a lower energy state, emitting UV light at a different wavelength. The Thermo Scientific 43iQ Sulfur Dioxide (SO2) gas analyzer utilizes pulsed fluorescence technology to measure the amount of sulfur dioxide in the air. The pulsing of the UV source lamp serves to increase the optical intensity whereby a greater UV energy throughput and lower detectable SO2 concentration are realized.
Utilizing unique Pulsed Ultraviolet Fluorescence (PUVF) technology and the proven Pyrolysis system, the SOLA iQ analyzer builds on the success of the SOLA II range of total sulfur analyzers with an install base of thousands of units for measuring total sulfur concentration at the world's leading oil & gas companies.
