The sulfur dioxide (SO₂) analyzer is a device used to measure the concentration of sulfur dioxide in a given sample. It is an important tool in the field of environmental monitoring, as sulfur dioxide is a major pollutant and a precursor to acid rain.
The analyzer works by measuring the amount of SO₂ in the air using a photo-optical method. A sample of air is drawn into the analyzer, and then a lamp is used to create a light beam which is then passed through a sample of the air. The amount of SO₂ present is determined by the amount of light absorbed by the sulfur dioxide molecules.
The sulfur dioxide analyzer is typically composed of four major components: a sample inlet, a light source, a detector, and a display. The sample inlet is where the air or gas sample is drawn in. The light source is usually an ultraviolet light which is used to create a light beam that is then passed through the sample. The detector measures the amount of light absorbed by the SO₂ molecules in the sample, and the display is used to show the results of the measurement.
The sulfur dioxide analyzer is an important tool for monitoring air quality in both indoor and outdoor environments. It is used to monitor sulfur dioxide levels in industrial areas as well as public places such as schools, hospitals, and transportation hubs.
It is also used in research laboratories to measure the amount of sulfur dioxide in the atmosphere, in order to understand the effects of air pollution on the environment. The sulfur dioxide analyzer is a vital tool for understanding and controlling air pollution, and is a key component of any air quality monitoring system.
The Global Sulfur dioxide analyzer market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The 6400T-H2S monitors hydrogen sulphide (H2S) by utilising a catalytic converter that is heated to 600°F (315°C) to convert H2S into SO2 while preventing the conversion of other, more difficult-to-oxidize sulphurs.
Analysing SO2 and H2S simultaneously is possible using a switching mode.Advanced colour displays, capacitive touch screens, user-friendly interfaces, versatile I/O, and integrated data collecting capabilities are all features of the 6400T series of analyzers.
It has an integrated feature that allows data to be acquired utilising the internal memory of the analyzer. This makes it possible to log a variety of characteristics, including calibration information, operating parameters like flow, pressure, and lamp intensity, and averaged or instantaneous concentration measurements.
To suit air monitoring requirements, the analyzers combine lower weight, tough construction, ease of use, sophisticated diagnostics, modular design, and exceptional performance.
The sample input stream containing sulphur dioxide to be analysed is sent into a reaction chamber in sulphur dioxide analyzers, where it is irradiated by an ultraviolet light source.
Fluorescence is the result of sulphur dioxide molecules absorbing incident radiation, temporarily increasing their energy content, and then releasing the absorbed energy at a wavelength longer than the incident radiation.
A photomultiplier tube detects the fluorescence radiation at an angle of right angles to the incident radiation. It then electrically amplifies the signal, which is then presented as a signal proportional to the amount of sulphur dioxide in the input gas sample.
Nitric oxide exhibits photoluminescence at a wavelength akin to that of sulphur dioxide. Applications of sulphur dioxide fluorescent analyzers, like measuring sulphur dioxide in vehicle exhaust emissions, are so afflicted by nitric oxide fluorescence that the indication of sulphur dioxide may be twice its true concentration, even though the majority of these applications only experience minor effects from nitric oxide.
Sulphur dioxide sample streams also contain other chemicals that glow similarly to sulphur dioxide. Nevertheless, it has since been discovered that nitric oxide’s interferent actions result in interferent fluorescence, and that these effects cannot be eliminated by previously developed techniques or equipment.
