For quantifying the trace gases that are existent in an air sample, an infrared gas analyzer is commonly utilized. If functions by measuring the various wavelengths that the gases will absorb radiation in order to recognize them. It is widely used for chemical and industrial applications, and is considered to be one of the most accurate forms of identification due to the unique spectra produced by each substance.
The whole device is composed of two chambers which will analyze and detect the components in the gases. One of the chambers is used for measuring the wavelengths, and the other is used as a standard for evaluation. The infrared light is then passed through one end of the chamber and will move through the different gases which are located in the chamber. Once the gas is captured in the compartment, the infrared light is directed through the sample toward the other end of the chamber where the detector is located. The detector is fixed with an optical filter in front of it that will block out other wavelengths that are not being measured. A definite identification can be made with extreme accuracy using infrared light because different gases or elements will not absorb the same wavelengths as any others.
The industrial applications for these analyzers make up a big portion of what they are used for, and they are often found in factories. The analyzers can be placed directly in the exhaust systems of a factory to record real-time data. The most dependable and accurate infrared gas analyzers operate with a single beam, dual-wavelength principle, which is what most industrial-made analyzers work with. Six gas-phase compounds can be monitored simultaneously using this type of mechanism because 8 different wavelengths are made available at one time.
Boilers, waste incinerators, and industrial furnaces are the most common locations where an infrared gas analyzer will be used. They are used both by private companies or industries and research facilities equally. Many companies are required to be equipped with this type of analyzer in order to remain in accordance with local laws. There are also times where they will be used to collect data for research applications.
Commonly when a stack-mounted infrared gas analyzer is used, it is for emissions monitoring. They are made to specifically measure the output of O2, CO2, CH4, NO, and other gases which are likely to pass through the stack. The concentrations of each of these gases as well as how much of each is present in the exhaust will also be able to be measured with this system.
This kind of monitoring is helpful to any company that has a plant that releases gaseous waste into the air, but several companies will install them in order to comply with local laws. These companies may decide to monitor their emissions in order to remain in compliance with the regulations set forth by their government. Many companies are also looking for alternatives or ways to reduce their CO2 emissions and environmental impact, so they might choose one of these systems as a way to monitor that.
