3 method summary

The interference light generated by the Fourier transform infrared spectrometer passes through the helium tetrachloride absorption cell after the beam splitter meets, and contains interference of sample information. The light reaches the detector, and then the signal is processed by Fourier transform to finally obtain the transmittance of the specified wave number.

4 instruments

4.1 Infrared spectrometer The Fourier transform infrared spectrometer has a wavenumber resolution of not less than 4 cm-1 and a transmittance accuracy of better than 0.1%. 4.2 Sample absorption pool Pool body. Corrosion-resistant, non-polluting products, wall thickness 2mm~4mm, outer diameter 24mm~26mm, length 100mm±0.1mm. With There are two inlet and outlet, the outer diameter is 6mm~8mm, and it is welded perpendicularly to the pool body. Window. 锗 single crystal polished sheet, thickness 2mm, the connection between the cymbal and the pool should ensure sealing. 4.3 Other The sample absorption cell, tubing, and all utensils should be cleaned and dried prior to use.

5 test environment

The relative humidity of the sampling and testing environment is not more than 45%, the temperature is 25 °C ± 2 °C, no vibration, no electromagnetic interference, no mechanical impact. ...
