WebOct 6, 2024 · There are various measurement methods in FTIR spectroscopy, and these are summarized below. Transmission methods. KBr tablet method. This method is used for powder samples, and precise measurements can be performed even with very small samples. However, due to the fact that KBr absorbs moisture, it is not suitable when … WebAs FTIR becomes more widespread, ATR method is a method that is once more attracting interest for its utility. ATR method is proving to be an extremely effective method, even for water solutions, which have been difficult to measure with other FTIR methods. It can be thought of as a method that only measures the extremely thin layer in close ...

WebMay 28, 2024 · Thick samples of neat liquids usually absorb too strongly to produce a satisfactory spectrum. For example, thick samples of carbon tetrachloride absorb strongly near 800 cm -1 ; compensation for this band (using a reference beam with pure solvent) is ineffective since strong absorption prevents any radiation from reaching the detector. WebWhat is FTIR? FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample.
