FTIR spectra reveal the composition of solids, liquids, and gases. The most common use is in the identification of unknown materials and confirmation of production materials (incoming or outgoing). The information content is very specific in most cases, permitting fine discrimination between like materials. The speed of FTIR analysis makes it particularly useful in screening applications, while the sensitivity empowers many advanced research applications.
The total scope of FTIR applications is extensive. Some of the more common applications are quality verification of incoming/outgoing materials; deformulation of polymers, rubbers, and other materials through thermogravimetric infra-red (TGA-IR) or gas chromatography infra-red (GC-IR) analysis; microanalysis of small sections of materials to identify contaminants; analysis of thin films and coatings; monitoring of automotive or smokestack emissions; and failure analysis.
The preservation of art and other antiquities requires a thorough understanding of the composition of the materials involved, including the impact of previous attempts at preservation (often involving some coating intended to protect the piece). The Thermo Scientific Nicolet Summit FTIR Spectrometer is regularly used at archeological sites because of its non-destructive nature and specificity in identification, particularly of fibers and dyes. Our microscopy and sample preparation expertise have enabled analysts to penetrate deep into compositions, including frescos on walls in Pompeii and Tintoretto paintings in Venice.

Use FTIR spectroscopy to perform gas analysis on a variety of samples, like well emissions, and ambient air monitoring. Whether you conduct fire science research, analyze emissions, or need to verify the purity of gases for semiconductor manufacturing, FTIR spectroscopy provides the insight you need to advance your research or keep your business competitive. FTIR spectroscopy produces a spectrum for gas samples that represents the molecular absorption and transmission response to certain wavelengths of light, creating a molecular “fingerprint” of the sample. This makes the technique useful for applications that require:
The Air Bag method analyzes the effluent emitted during air bag inflation. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector.
Measuring challenging compounds like ethylene oxide requires technology that avoids false alarms for benign interferences and meets standards from regulatory bodies such as the Environmental Protection Agency (EPA) and US Occupational Safety and Health Administration (OSHA). Successful ambient air monitoring requires the ability to discriminate target compounds down to single-digit ppb even in the presence of high concentrations of interferences, such as water, solvents, and hydrocarbons.
Aviator’s Breathing Oxygen
The Aviator’s Breathing Oxygen (ABO) method is designed to detect impurities in ABO gas according to the US Air Force military standard 1564A. This method is used with the 10-meter gas cell. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector.
Bulk gas qualification
Measurement of trace contaminates in N₂, O₂, H₂, Ar, Kr, and CO² used in semiconductor, medical, food and beverage and energy.

In addition, system-level product offerings are easily automated, providing multichannel sampling and factory reporting.
Compressed breathing air
The Compressed Breathing Air (CBA) method analyzes CBA for impurities. This method is used with the 10-meter gas cell. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector.
Engine exhaust emissions
Raw exhaust methods provide measurement of engine exhaust emissions from either spark-ignition or diesel engines. These methods cover concentration ranges found in the exhaust gas without dilution, with gas samples taken either before or after the catalytic converter. Gasoline vs Diesel methods differ in the concentration range of several components, as diesel exhaust differs from spark-ignition engine exhaust due to excess air. FTIR is an excellent technique to study Selective Catalytic Reduction (SCR) compounds, including NO, NO₂, N₂O, and NH₃. These methods are configured with the Thermo Scientific 2-meter gas cell and a liquid-nitrogen cooled MCT-A detector. Detection limits are based on a 3-second sample time.
The fire science method is configured to analyze toxic gases generated during the combustion of building materials, including those defined under the EN 45545-2 Railway smoke toxicity standard. The method can be used with cone calorimeters, smoke boxes, or ambient sampling of combustion experiments. The FTIR is configured with a heated 2-meter pathlength cell for most fire science applications, or a longer-path 10-meter cell may be used for diluted samples. Detection limits are based on a 3-second sample time with a liquid-nitrogen cooled MCT-A detector.
Ideal for a wide range of in-process monitoring applications, FTIR provides automated end-product quality assurance in the semiconductor industry, chemical manufacturing, and air separation. Because FTIR is an optical technology that requires no calibration it can run for months or longer without any intervention. This dramatically reduces operating cost and is ideal for production facilities or remote locations.
FTIR is an excellent technique for analyzing gases generated by new renewable energy developments, such as pyrolysis of wood chips or anaerobic digestion of garbage or manure. Synfuels and biogases produce environmental emissions, such as methane and other potentially harmful gases, during power generation. They also cause harmful effects on the combustion chambers or compressors. Hydrogen gas used for fuel cells must be pure of contaminants which can be detected using FTIR. FTIR spectroscopy offers powerful capabilities to analyze hydrogen, synfuel and biogas components, enabling researchers to optimize their gas generation and collection techniques.
Gas applications that require high accuracy and stable calibrations can benefit from FTIR strengths. FTIR gas analysis can be used in specialty gas manufacturing, semiconductor purity testing, and identification of contaminants in O₂ or breathing air.
