There are several different gas measurement methods used for continuous emission measurement system and process gas analysis. The most common and most popular of these methods is the infrared technology. Each measurement sensor is based on a single target gas in infrared technology. And therefore, infrared technology alone is not sufficient in some specific parameters and multiple gas measurements. Accordingly, FTIR (Fourier Transform Infrared) Technology has been developed.
The most common application areas of this technology, which can simultaneously measure multiple parameters, are CEMS (Continuous Emission Measurement Systems), laboratory, R&D and quality practices.
FTIR Spectroscopy is a technique that provides the structural and functional information resulting from the vibrations of the functional groups of the sample macromolecules to be examined. This method is an improved form of regular IR spectrometer. IR spectrometer is designed as double beam path. In FTIR, the beam from the IR source is converted into IR beams at different frequencies with diffraction prisms, just as the sun’s rays break down and create the rainbow. IR beam at each frequency passing through the sample cell is recorded to obtain the IR spectrum of the analyzed sample.
Infrared spectrum of a gas is like a fingerprint: each component has a unique molecular structure or a unique combination of atoms. When exposed to infrared light, they generate an infrared spectrum. Based on their unique structure, it is possible to identify and measure each compound (except for diatomic molecules).
Most gases absorb infrared light at some wavelengths in the infrared spectrum. The intensity of absorption depends on the molecular structure of the gas, therefore, each gas has a different absorption scheme.
FTIR (Fourier Transform Infrared) Spectrometer
A FTIR analyzer simultaneously scans the entire infrared spectrum to calculate the concentrations of each gas in the sample. Scanning the entire infrared spectrum at once means that all gases in the sample can be measured simultaneously. Thanks to this feature in FTIR, it is possible to add new compounds easily without any changes in the software since all gases are measured by scanning the same infrared spectrum.

FTIR technology is an ideal solution for a variety of applications which require a rapid measurement of a great number of gases accurately and reliably.
What are the advantages of FTIR Technology?
Being futureproof and capacity of measuring a large number of gases, FTIR Technology is more advantageous than other measurement methods.
1. Futureproof
One of the best features of FTIR is that all gases are measured with the scanning of the same infrared spectrum. Hence, it is possible to add new gases and gas intervals easily without making any changes to the equipment or changing the analyzer.
It can easily adapt to the amendments that might be made in regulations related to the emissions measurement system (such as low emission limit value (ELV) and certificate updates. Gasmet gas analyzers are not only able to monitor today’s emission limits, but also the low limit values that might occur in the future, making FTIR a future-oriented solution and turning it into a longterm investment.
2. Multicomponent Capability
The ability of FTIR to measure a high number of gases indicates that it is unrivaled among other emission measurement technologies. All components can be measured and analyzed at a sigle time.
3. Certificate
Gasmet FTIR emission measurement system are certified by TUV and MCERTS (KGS1 / QAL1). Many components such as formaldehyde, low-range HF and NO are included in the certificate.
*Formaldehyde: It is an organic compound with the formula; CH2O. It is the simplest member of aldehydes. It is also known as Methanal.
4. Reliability
Having the sensitivity of recognizing very low gas concentrations, Fourier Transform Infrared spectroscopy is one of the most reliable technologies. Gasmet FTIR gas analyzers can perform measurements from low ppm levels to vol. % levels.
As specified in the certificate, the maintenance period is 6 months. The reliability of the system is proven once again with this period.
