Fourier Transform infrared (FTIR) spectroscopy is a technique that detects chemical bonds in molecules by generating infrared absorption spectra of solids, liquids, or gases.
Sample dry without water, more than 10mg, more than 200 mesh, can be used for direct tablet size.
The sample must be non-toxic and non-corrosive; Provide more than 2mL, the sample as far as possible without water (water samples, water peak will greatly interfere with the sample spectrum).
the sample is dry and water-free, larger than 0.5cm*0.5cm, hard block/film sample is difficult to peak.
For samples that are easily deliquescent, please prepare a dryer by the user.
For volatile, sublimated and heat-unstable samples, please use containers with sealed caps or stopper and cover tightly. At the same time, the storage conditions of samples must be indicated.
