Online CEMS 5 gases (Nox, Sox, CO2, Co, O2) UV Gas Analyzer
The analyzer based on UV absorption spectroscopy and chemometric
algorithms to measure SO2, NOx, O2, NH3, Cl2, O3, H2S and other gases concentration, with high accuracy, high reliability, fast response time, wide
application and other characteristics, the indicators have reached
or exceeded similar products, it can be widely used in
environmental online monitoring, industrial control, security
monitoring and other occasions.
>>>Key Features
Full spectrum measurement and DOAS (Differential Optical Absorption
Spectroscopy) algorithm, excelling in accuracy, repeatability and
anti-interference with moisture, dust.
Modular design and no moving parts, higher reliability and easier
maintenance.
Pulse Xenon Lamp used as light source with over 10-year lifetime.
The adoption of diode array sensor enables instant spectrum
acquisition and rapid response.
>>> Features and Benefits
1. Analyzer uses the following optical technology platform to get
the UV absorption spectrum, the technology platform consists of
light source, gas chamber, fiber optics and spectroscopy (including
the diaphragm, holographic gratings, linear array detector) and
other optical components.
2. UV-visible light emitted by the optical window into the gas
chamber, is absorbed by the sample gas flowing through the measured
gas chamber, carrying the tested sample gas absorbs light through
the lens after gathering information coupled into optical fiber
through the optical fiber transmission into the spectrometer
splitting, sampling, to obtain the absorption spectrum of the gas.
3. Use DOAS technology spectrum analysis, can analyze the
concentration of the gas in the relevant component.
>>> Measuring principle
1) The light source emits ultraviolet beam which transfers to gas
cell through optical fiber.
2) After absorption by measuring gas, the light beam transfers
through optical fiber to spectrometer.
3) Being dispersed through the grating, and converted into electric
signal by the array sensor, a continuous absorption spectrum of
measuring gas is thereafter obtained.
>>>Technology Comparison
| Item | UV Hot-Wet Method | NDIR |
| Spectral Range | Complete and continuous absorption spectra obtained through
holographic grating and diode array detection | Non Dispersive, characteristic absorption spectra obtained through
band-pass filter |
| Linear Response | High wavelength resolution secures linear response | band-pass filtration compromises linear response |
