Explanation:
Detailed explanation-1: -Which of the following is not the advantage of Fourier Transform Spectrometers? Explanation: The instrument is not easy to maintain and it is a disadvantage. The other disadvantage is that the cost is high.
Detailed explanation-2: -FTIR is sometimes confused or blinded by water. Like Raman, it cannot see elements, simple ionic compounds, and purely ionic acids in water.
Detailed explanation-3: -The sampling chamber of an FTIR can present some limitations due to its relatively small size. Mounted pieces can obstruct the IR beam. Usually, only small items as rings can be tested. Several materials completely absorb Infrared radiation; consequently, it may be impossible to get a reliable result. 31-Jul-2019
