Identifying unknown materials can be tedious at times, but there is a form of infrared scanning that addresses that issue. It’s none other than the Fourier-transform infrared spectroscopy, or FTIR. In this article, we’ll learn the FTIR Spectroscopy overview. At the same time, we’ll know how it works and where it is used.
How Do You Define FTIR Spectroscopy?
FTIR or Fourier-transform infrared spectroscopy is the most common or frequent type of infrared spectroscopy. It works when infrared radiation permeates through a sampled item; the item absorbs some of the radiation. On the other hand, radiation that does pass through the item is recorded.
Since the item contains many molecules, each one will emit a different spectrum or color. These colors are then utilized to identify the molecules in the sampled item. As a result, one will get to know the sample’s composition. They can deem whether this item is safe to use or not.
FTIR tends to be the preferred spectroscopy method for a few specific reasons. First, FTIR doesn’t destroy the sample. Second, it is faster and more efficient than the older infrared spectroscopy techniques. Lastly, it is more precise and accurate in providing results.
Where Does FTIR Spectroscopy See Use?
FTIR has a wide scope or coverage of what areas it can apply to. We’ll cover some areas where it sees a lot of use. By seeing the various applications FTIR uses, you might consider using Agilent FTIR spectroscopy instruments for your lab or facility. With that said, here are some of the fields where FTIR sees a lot of use:
FTIR for Identifying Battery Materials
You can use FTIR analysis to check the quality and composition of batteries. Results provided by the FTIR scan can be used to improve and optimize future Lithium Batteries and their alternative versions. FTIR spectroscopy’s quick-acting and non-destructive nature makes it a recommended choice for battery quality and safety assurance.
FTIR for use in Environmental Sciences
FTIR analysis is handy for studies in environmental science – FTIR is employed to check air, water, and soil quality. The results that come from this form of infrared spectroscopy should give you indicators of whether there is pollution or not.
FTIR for Analyzing Food and Beverages for Consumption
Factories use FTIR spectroscopy to ensure that their food and beverages meet the customer’s standards. At the same time, meeting these standards increases the factory’s production and income.
Another good application of FTIR is Food Administrations using it to check whether the products are safe to consume. For example, imported consumables have arrived in your country. The Food Administration will take one of those imported goods as a sample item and have them scanned under FTIR.
Once the FTIR scans yield their results, they can declare whether it’s safe to consume or it will need to be recalled and replaced.
FTIR for Toxicology Studies
FTIR can also be used in Toxicology studies. Whenever scientists face an unknown material, they use FTIR spectroscopy to identify the molecules within the material. Once identified, they can conclude that the material has toxic or hazardous materials.
FTIR for Forensic Studies and Investigation
Fourier-transform infrared spectroscopy also sees use in criminal investigations. By scanning items gathered from the crime scene, they could identify molecules of fluids that may have been used in the incident. Quite similar to how FTIR is used for Toxicology studies.
FTIR, Reliable and Applicable in Many Situations
Fourier-transform infrared spectroscopy has many applications due to its accuracy and efficiency. It can see use in various areas ranging from food and health to environmental studies. It’s no wonder why this form of spectroscopy is the most commonly used type. It shows that FTIR applies in many situations but can provide and deliver the results you are looking for.
