What are the principles of measuring CO2 gas ?
Measuring CO2 gas involves the use of two main technologies: Tunable Diode Laser Absorption Spectroscopy (TDLAS) and Non-Dispersive Infrared (NDIR).
TDLAS is a relatively new technology that relies on the absorption of light in order to measure the concentration of CO2 in a gas. It uses a laser to detect the molecules in a sample, and then calculates the concentration based on their optical absorption. This technique is advantageous in that it has a high degree of accuracy, can measure small concentrations, and does not require calibration with reference gases .
Non-dispersive infrared (NDIR) is a more traditional method of measuring CO2 gas. This technique relies on the infrared absorption of CO2 molecules and the detection of infrared radiation by an optical detector. NDIR is typically used to measure larger concentrations of gases, but it is not as accurate or sensitive as TDLAS. Additionally, NDIR requires calibration with reference gases in order to properly measure the concentrations of CO2 in a sample.
ESE-IR-100 CO2 gas analyzer is a new type of infrared gas sensor independentlydeveloped by our company for environmental monitoring and industrial site emission gas analysis. High-precision, high-resolution probes and gas absorption cells with completely independent intellectual property rights are used. The sensor has the characteristics of high precision, good stability and fast response time.
A CO2 gas analyzer that utilizes NDIR (Nondispersive Infrared) technology is a device specifically designed to measure the concentration of carbon dioxide (CO2) in a gas sample using the NDIR principle. NDIR technology has become a widely adopted method for CO2 gas analysis due to its accuracy and reliability.
In NDIR-based CO2 gas analyzers, the working principle involves the measurement of the absorption of infrared light by CO2 molecules. The analyzer emits infrared light at a specific wavelength that is absorbed by CO2, while other gases in the sample do not absorb significantly at that wavelength. By measuring the amount of light absorbed, the analyzer can determine the CO2 concentration in the gas sample.
Here’s a simplified overview of how an NDIR CO2 gas analyzer works:
Infrared Light Source: The analyzer includes an infrared light source, typically an infrared LED or a tunable infrared laser diode. The light source emits infrared light at a specific wavelength that corresponds to the absorption band of CO2.
Gas Sample Chamber: The gas sample is introduced into a measurement chamber or cell, which allows the infrared light to pass through it.
Detector: A detector is positioned on the other side of the gas sample chamber to measure the intensity of the transmitted light. The detector detects the remaining infrared light after it has passed through the gas sample.
Reference Channel: The analyzer may also include a reference channel that measures the intensity of light that has not passed through the gas sample. This reference measurement helps compensate for any variations in the light source intensity or other factors that can affect the measurement.
Signal Processing: The analyzer processes the signals from the detector and reference channel to determine the absorption of light by the CO2 molecules in the gas sample. The absorption signal is then converted into a CO2 concentration reading.
NDIR-based CO2 gas analyzers offer several advantages, including high accuracy, stability, and low sensitivity to other gases present in the sample. They are commonly used in applications such as indoor air quality monitoring, greenhouse gas monitoring, combustion processes, and industrial emissions control.
When selecting an NDIR CO2 gas analyzer, important factors to consider include the measurement range, accuracy, response time, calibration requirements, data logging capabilities, and any specific application requirements.
What is the application of CO2 measurement ?
CO2 monitoring is important in order to accurately assess the amount of CO2 emissions produced during different industrial activities.
In the metallurgical industry, monitoring of CO2 emissions can be used to evaluate the efficiency of the smelting process. This can be done by measuring the amount of CO2 generated during the process.
In landfills, CO2 is a by-product of landfill gas and the monitoring of this gas can be used to measure the efficiency of the landfill operations. The gas mainly contains CO2 and CH4, and if it is used for combustion or power generation, CO2 can also be used to evaluate the efficiency.
In vehicle carbon emissions, CO2 is a major greenhouse gas and monitoring of this emission can effectively measure which types of vehicles produce a large amount of CO2. This can help in developing strategies to reduce the emission of this greenhouse gas and help fight climate change.
Overall, CO2 monitoring is an important tool for assessing the amount of CO2 emissions produced during different industrial activities. By measuring and monitoring these emissions, it can help in reducing greenhouse gas emissions and the effects of climate change. By doing this, it can also have a positive effect on the environment.
Measuring carbon dioxide (CO2) is important for understanding the role it plays in the environment and its effect on climate change. CO2 is a major component of Earth’s atmosphere, and it traps heat like a blanket, causing global temperatures to rise. Too m uch CO2 can lead to drastic changes in our weather patterns and ecosystems, so monitoring its levels is essential for predicting future climate conditions. Additionally, measuring CO2 can help us better understand our impact on the environment and make informed decisions about how to reduce emissions and slow down down down down down global warming. By analyzing CO2 data over time, we can develop strategies to mitigate the effects of climate change and ensure a sustainable future.
Before industrialization, the global average annual atmospheric carbon dioxide concentration was 278ppm (1ppm is one part per million). In 2012, the global annual average atmospheric carbon dioxide concentration was 393.1ppm. By April 2014 , the monthly average carbon dioxide concentration in the northern hemisphere atmosphere exceeded 400ppm for the first time. . 2. Global climate warming, the continuous aggravation of the atmospheric greenhouse effect leads to global climate warming, resulting in a series of global climate problems that cannot be predicted by today’s science. According to the International Climate Change Economics Report, if human beings maintain the current way of life, by 2100, there will be a 50% chance that the global average temperature will rise by 4°C.
