EM-5 Gas Analyzer (UV-DOAS + NDIR)

EM-5 gas analyzer (UV-DOAS + NDIR)is applied for online gas analysis of industry stack emissions. It is combined with two advanced measuring technologies: UV Differential Optical Absorption Spectroscopy (UV-DOAS) technology  +  Non-Dispersive Infrared (NDIR) technology.  

The analyzer can measure the gas concentration of SO₂, NO, NO₂, CO, CO₂, O₂  simutanuously. Other gas components like Cl₂ can also be measured through configuring modules. One analyzer can measure up to 6 gas components  simutanuously. The analyzer is featured with low detection limit, high measurement accuracy and reliability, fast response.

Features                 

•  Adopt Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS) + and Non-Dispersive Infrared (NDIR) technology .

• Module design, flexible to be configured with various gas measuring module to meet with different measure range and accuracy requirement.

• Long Optical Path measuring chamber (15m optical path) can be configured, suitable for ultro-low range measurement, high sensitivity.

• The measuring chamber adopts multiple reflection technology, detection limit as low as 0.1 ppm;

• The pulsed xenon light source has more than 10 years service life.

• The NO and NO₂ can be measured simultaneously ; NO₂/NO converter is not needed.

• No optical moving parts, not affected by vibration;

• Constant temperature and heating companion, avoid the impact of the temperature fluctuation

• Not affected by background gases such as H₂O, CH₄, CO, NH₃, dust,etc;

• No cross interference between measured gases;

• Customizable to meet the OEM and ODM needs for customer.

Application            

Typical application of industry process

•  Continuous flue gas emission monitoring for power plants (analyze SO₂, NOx, and O₂);

•  Desulfurization process monitoring (analyze SO₂ and O₂)

•  Denitrofication process monitoring (analyze NOx, NH₃ and O₂)

•  Continuous flue gas emission monitoring of waste incineration (analyze SO₂, NOx and O₂)

•  Trace Cl2 analysis in PVC process and titanium dioxide production process in chlor-alkali plants (analyze Cl₂)
