回答：Abstract: Because FTIR technique is a eedy and easily operated qualitative analysis for a liquid sample, it can meet the requirement to monitor and to control a production line or research experiments. FTIR analysis is commonly used for a liquid sample analysis. However, the preparation of the liquid sample, the condition and settings of the experiment, and the analysis of the spectrum significantly influence the results and conclusions. This study showed that the absorption strength of a liquid sample to infrared light is easily influenced by the state of the sample, the type of the solvent, and the concentration of the solution, as well as the signal-to-noise ratio. By comparing the spectra with varying factors, the experiment has concluded that both the concentration and uniformity of a liquid sample may help increase the signal of the FTIR spectrum and the gain setting of the FTIR instrument also has obvious impact on the spectrum.
