Nowadays Attenuated Total Reflectance (ATR) accessories are the most commonly used technique in FTIR analysis. Conventional, time-consuming sample preparation methods such as KBr pellet and Nujol mull have now beyond in favor of using diamond ATR that do not need preparation of the sample, and which are used in a wide variety of sample types.
The Advantages Attenuated Total Reflection Technique (ATR) are as follows:
The Advantages Attenuated Total Reflection Technique (ATR) are as follows:
- There is no required for preparation of samples, this is a major advantage of ATR. The sample has to be placed directly on the ATR sample point.
- The minimum amount of sample is required.
- It is a time-saving technique.
- The simple and fast cleaning-just remove the sample and clean the crystal surface
- No pellet pressing or grinding is required to collect spectrum
- A wide range of sample types such as solids, liquids, gels, powders, and pastes in the entire pH range can be analyzed.
- This gives high-quality spectra over the entire range of the infrared region (4000–400 cm-1).
- Diamond ATR is chemically inert, very strong, and high resistance to scratches.
