WebOct 12, 2024 · FTIR stands for ‘Fourier-transform infrared’ spectroscopy: a technique that can be used to procure an infrared spectrum of either the emission or absorption of a liquid, solid, or gas sample. An FTIR spectrometer synchronously collects the data of high-spectral-resolution over an extensive range. WebThe ATR-method is qualified for measuring aqueous solutions if the multiplereflection technique is used in such a way that strong water absorptions do not cover a large part of the information on the spectrum. The single-reflection technique is mainly suitable for solutions of 2-molar and higher concentrations. Organic acids, phenols, amides, …
