Luke Purdie
Product Manager

Our range of carbon dioxide analyzers delivers the reliable and accurate measurements your process needs, using a choice of sensing technologies such as including Infrared, Plasma, and Gas Chromatography. Our products include CO2 combustion analyzers and CO2 purity analyzers, and are available as hazardous area, safe area, and portable instruments.

Why measure Carbon Dioxide ?

A common byproduct of combustion, carbon dioxide is a colorless gas which absorbs infrared radiation, acting as a greenhouse gas. It is closely regulated around the world as a harmful emission from many power generation and industrial manufacturing processes, and so must be monitored using CO2 gas analyzers. It is also a versatile industrial material, used in inerting operations and as a feedstock for the synthesis of fuels and chemicals. A CO2 gas analyzer may also be needed to monitor carbon dioxide as a trace impurity in industrial, medical, or semiconductor gases.

How CO2 gas analyzers work to measure carbon dioxide

A number of sensing technologies are available for our carbon dioxide gas analyzers. The most appropriate solution depends on the application, and the measurement range required.

  • Infrared sensing is a flexible measurement technology based on the unique light-absorbing properties of some gases, delivering a non-contact, real-time detection of the selected gas’s concentration in a mixture.
  • Gas Chromatography separates out the constituent components of a gas mixture, allowing relative concentrations to be determined. Under optimized conditions, it can measure down to parts-per-billion (ppb) levels, making it ideal for high-purity control processes.
  • Servomex’s Plasma emission detection technology was developed to provide a safer alternative to flame-based sensing for hydrocarbon analysis, and delivers ultra-low measurements. It provides highly sensitive and selective speciation, so is only suitable for trace analysis applications.
  • Spectroscopic technology combines innovative Infrared absorption spectroscopy, using advanced spectral scanning, with chemometrics, to deliver a high-quality optical measurement that is both accurate and highly stable.

 

SERVOPRO Servomex 4900 Multigas

Our key application solutions

Measuring CO2 emissions is a key part of any industry’s clean air strategy. The SERVOPRO 4900 Multigas CEMS analyzer provides continuous monitoring at ppm or percentage levels. For carbon capture processes, the versatile SERVOPRO MultiExact 4100 or MultiExact 4200 multi-gas analyzers are recommended.

Industrial process control measurements can be made by the SERVOTOUGH SpectraExact 2500 – for example in the manufacture of ethylene or ethylene dichloride. Because it is present in atmospheric air, CO2 is a common contaminant in ultra-high purity gases. The trace and ultra-trace measurement capabilities of the SERVOPRO Chroma, NanoChrome, and NanoChrome ULTRA make these CO2 gas analyzers ideal for this application.

Our solutions for Carbon Dioxide gas analysis

Servomex has a variety of carbon dioxide gas analyzer solutions available to suit different applications. For hazardous area processes, the SERVOTOUGH range includes the SERVOTOUGH SpectraExact 2500 photometric analyzer, which measures CO2 using Infrared and Spectroscopic sensing respectively. Infrared sensors also power our portable SERVOFLEX CO2 analyzers, the MiniMP 5200, and MiniHD 5200. Our safe area CO2 analyzers are in the SERVOPRO product range, and include the Infrared-sensing 4900 Multigas, MultiExact 4100 , and MultiExact 4200 multi, along with the Chroma, NanoChrome, and NanoChrome ULTRA, which all use Plasma sensing combined with Gas Chromatography.
