Non-Dispersive Infrared (NDIR) gas analyzers are widely used in various industries and applications for the measurement and analysis of gas concentrations. NDIR analyzers utilize the principle of infrared absorption to determine the presence and concentration of specific gases in a sample. These analyzers are known for their accuracy, reliability, and ability to measure trace gas concentrations.

Here are some key features and components of NDIR gas analyzers:

1. Infrared Light Source: NDIR analyzers use an infrared light source that emits infrared radiation at specific wavelengths. The light source is typically an infrared light-emitting diode (IR LED) or a heated filament. The emitted light contains wavelengths that correspond to the absorption bands of the target gas.

2. Gas Sample Chamber: The gas sample to be analyzed is introduced into a gas chamber or optical cell. The gas chamber is designed to allow the infrared light to pass through the gas sample. The length of the gas chamber is optimized to ensure sufficient interaction between the gas molecules and the infrared light.

3. Optical Filters: NDIR analyzers incorporate optical filters to selectively transmit the infrared wavelengths that are absorbed by the target gas. The filters help to eliminate other wavelengths of infrared light that could interfere with the measurement. The selection of appropriate filters depends on the specific gas being analyzed.

4. Detector: On the opposite side of the gas chamber, a detector is placed to measure the intensity of the transmitted infrared light. The detector is typically a thermopile or a pyroelectric sensor that converts the infrared radiation into an electrical signal. The signal is proportional to the intensity of the transmitted light, which is affected by the absorption of the target gas in the sample.

5. Reference Channel: To compensate for changes in the light source intensity and other interferences, NDIR analyzers often include a reference channel. The reference channel measures the background or reference signal, which represents the unabsorbed infrared light. By comparing the reference signal with the signal from the gas sample, the analyzer can accurately determine the gas concentration.

6. Signal Processing and Analysis: The electrical signals from the detector and reference channel are processed and analyzed by the instrument's electronics. The analyzer applies calibration factors and algorithms to calculate the gas concentration based on the measured signals. The concentration is displayed on the analyzer's screen or transmitted to an external system for further analysis and recording.

NDIR gas analyzers offer several advantages, including high sensitivity, selectivity, and stability. They can measure gas concentrations ranging from percent levels down to parts per million (ppm) or even parts per billion (ppb). NDIR analyzers are commonly used for the analysis of gases such as carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), nitrous oxide (N2O), sulfur dioxide (SO2), and various hydrocarbons.

These analyzers find applications in environmental monitoring, industrial emissions control, indoor air quality assessment, combustion analysis, process control, and research laboratories. They are utilized in fields such as air pollution monitoring, automotive emissions testing, greenhouse gas monitoring, industrial stack emissions monitoring, and safety monitoring in confined spaces.

It's worth noting that the accuracy and performance of NDIR gas analyzers heavily depend on proper calibration, maintenance, and periodic verification against certified gas standards.

NDIR gas analyzer  IR-GAS-600 this model high-stability infrared detectors for simultaneously measuring CO, CO2, and CH4. H2 always reads correctly, independent of the background gas composition. An optional non-depleting paramagnetic sensor can be used to conduct O2 analysis. All sensors/detectors are temperature-controlled or temperature-compensated for maximum analytical stability.

Both types of analyzers are available with analysis of:

• Carbon Monoxide (CO) via infrared detector
• Carbon Dioxide (CO2) via infrared detector
• Oxygen (O2) via electrochemical sensor or optional paramagnetic
• Methane (CH4) via infrared detector
