FTIR Multi-Gas Analyzer Gas Analyzers Portable Model Monitor More Than 10 Gases

Here are some key details about FTIR ( Fourier Transform Infrared Spectroscopy ) Multi-Gas Analyzers:

- Utilize FTIR technology to provide continuous measurements of multiple gases simultaneously from a single sample.
- Infrared light passes through the gas sample, and absorption occurs at specific wavelengths unique to each gas.
- Michelson interferometer modulates the IR beam to generate an interferogram, which is decoded into a spectrum.
- The spectrum provides qualitative and quantitative analysis for each gas component.
- Can measure a wide range of gases including hydrocarbons, toxic gases, pollutants, and more.
- Typical gases measured: CO2, CO, NOx, SO2, VOCs, CH4, NH3, HF, HCl, C2H2.
- Detection limits ranging from ppm to ppb levels depending on the gas.
- Measurement time from seconds to minutes. Provides continuous real-time monitoring.
- Immune from drift so usually no frequent calibration required after initial setup.
- Suitable for hazardous areas when combined with proper sample handling system.
- Applications include ambient air monitoring, industrial process and emissions monitoring, gas leakage detection.
- Used across industries like petrochemical, oil and gas, energy, pharmaceuticals, automotive.
- Major suppliers are MKS Instruments, ABB, Siemens, Emerson, Gasmet Technologies, Teledyne Analytical.
- Provides efficient multi-component analysis from one sample compared to multiple single-component analyzers.

In summary, FTIR multi-gas analyzers leverage FTIR spectroscopy for real-time quantitative monitoring of multiple gases simultaneously.
