When it comes to alternatives to Fourier-transform Infrared Spectroscopy (FTIR), there are several methods that can be just as effective, depending on your specific needs. These alternatives include attenuated total reflection (ATR) and diffuse reflectance infrared Fourier transform (DRIFT). Both techniques are widely used in various fields such as chemistry, medicine, biology, and geology.
What are the alternatives to FTIR? (3 Key Techniques Explained)
1. Attenuated Total Reflection (ATR)
ATR is a method that allows for the direct measurement of powder samples. It involves pressing the sample against a high-refractive-index prism. The infrared spectrum is then measured using infrared light that is totally internally reflected in the prism. A zinc selenide (ZnSe) or germanium (Ge) prism is typically used in the ATR accessory. Compared to other methods, ATR is an excellent way to obtain infrared information for the powder sample surface.
2. Diffuse Reflectance Infrared Fourier Transform (DRIFT)
DRIFT is a diffuse reflection method that has become widely used as FTIR has become more common. It involves measuring the infrared spectrum of powder samples mixed in a medium such as KBr or liquid paraffin. This method does not require the direct measurement of powder samples and is a popular alternative to traditional methods like the KBr pellet method and the Nujol method.
3. Flexibility in Sample Analysis
Both ATR and DRIFT provide alternative ways to analyze the properties of matter using infrared spectroscopy. They offer flexibility depending on the sample form and the requirements of the analysis. Whether you're working in chemistry, medicine, biology, or geology, these techniques can be tailored to meet your specific needs.
