  • Page 13: Principle Of Measurement

    DX4040 INSTRUCTION AND OPERATING MANUAL (E2.04) 3 PRINCIPLE OF MEASUREMENT 3.1 Principles of Infrared Spectroscopy Infrared (IR) spectroscopy is a technique for chemical analysis and determination of molecular structure in solid, liquid, and gas state. The principles that molecular vibrations occur in the infrared region of the electromagnetic spectrum and functional groups in chemical compounds have characteristic absorption frequencies are the basis of this technique.

  • Page 14: Figure 1. The Four Normal Modes Of Vibration Of Carbon Dioxide Co 2 Molecule

    DX4040 INSTRUCTION AND OPERATING MANUAL (E2.04) Figure 1 shows how a carbon dioxide CO molecule behaves when it interacts with infrared radiation. All different vibrations, rotations, and their combinations result in absorption bands of specific wavelengths of the infrared radiation.

An absorbance spectrum of carbon dioxide CO measured with a DX-4015 model. c(CO ) = 50 ppm, T = 50 C, absorption path length = 9.8 m. 3.2 Components of a Fourier Transform Infrared Spectrometer Figure 3 shows the basic parts that are typical for all non-dispersive FTIR spectrometers.

  • Page 16: Figure 4. A Michelson Interferometer Is A Unique Part Of An Ftir Spectrometer

    DX4040 INSTRUCTION AND OPERATING MANUAL (E2.04) The unique part of an FTIR spectrometer is the interferometer. Figure 4 shows a Michelson type interferometer. A mirror collects and collimates the infrared radiation from the source before it strikes the beam splitter. The beam splitter ideally transmits one-half of the radiation, and reflects the other half.

The spectrum is computed from the digitized interferogram by performing a Fourier transform by a computer utilizing a Fast Fourier Transform (FFT) algorithm. 3.3 Quantitative Analysis of FTIR Spectra The basic law for spectroscopic quantitative analysis is Beer's law (also known as the Beer-Lambert law).

  • Page 18: Multi-Component Analysis

    DX4040 INSTRUCTION AND OPERATING MANUAL (E2.04) absorbance is directly proportional to the concentration of the sample gas at a given wavelength. Since Beer's law is additive, the total absorbance A is equal to the sum of the values of A of each gas component.

  • Page 19: The Spectral Resolution Of Ftir Analysis

    DX4040 INSTRUCTION AND OPERATING MANUAL (E2.04) For example, suppose we have a sample spectrum and reference spectra like those shown in Figure 6. In this case, we know that the sample gas consists of gases Reference 1 and Reference 2. We have the reference spectra available and we know that these reference spectra represent concentrations of 10 ppm and 8 ppm, respectively.
  • Page 20 DX4040 INSTRUCTION AND OPERATING MANUAL (E2.04) This makes the use of low resolution quite worthwhile. To achieve precise quantitative analysis results, a low-resolution measurement should be used if the spectral analysis program can mathematically solve the spectral overlap. There are two reasons for the increase of the signal-to-noise ratio of an FTIR spectrum: •...
