FTIR Testing and Analysis: A Comprehensive Guide FTIR (Fourier Transform Infrared) spectroscopy is a versatile analytical technique that is used to identify and analyze compounds by measuring the absorption or transmission of infrared light. FTIR testing can be used in a wide range of applications such as food and beverage industry, pharmaceutical industry, forensic science, and environmental science, to name a few. To give you a better understanding of what FTIR testing and analysis is all about, let’s delve into some of the key concepts and applications of FTIR. Firstly, how does FTIR testing work? In simple terms, FTIR spectroscopy works by measuring the interaction between infrared light and a sample material. When the infrared light passes through the sample, some wavelengths are absorbed by the molecules in the sample, and others are transmitted. The resulting spectrum is compared to reference spectra to identify the compounds present in the sample. FTIR testing can be used to detect a wide range of compounds including organic and inorganic compounds, polymers, and biological molecules. The technique is particularly useful for identifying functional groups, such as carbonyl groups (C=O), hydroxyl groups (OH), and amino groups (NH2), which are commonly found in the structures of organic molecules. Now that we know how FTIR works and what it can detect, let’s explore some of its applications. In the food and beverage industry, FTIR testing can be used to identify and quantify additives, contaminants, and other compounds in food and drink products. It can also be used to analyze the composition and quality of raw materials and finished products, and to determine the shelf life of products. In the pharmaceutical industry, FTIR analysis is used to identify and quantify active pharmaceutical ingredients (APIs) and excipients, as well as impurities and degradants. It can also be used to determine the quality and consistency of finished products, and to monitor the stability of products over time. In forensic science, FTIR testing is used to identify unknown substances found at crime scenes or in drug seizures. It can also be used to analyze fibers, paints, and other trace evidence. In environmental science, FTIR spectroscopy is used to analyze soil and water samples for contaminants, such as pesticides, herbicides, and pollutants. It can also be used to monitor air quality and to analyze atmospheric gases. Overall, FTIR analysis is a powerful and versatile analytical technique that can be used in a wide range of applications.
