Fourier Transform Infrared Spectroscopy (FTIR) is a versatile analytical technique widely used across various industries and research fields. It is primarily employed to identify and analyze the chemical composition of materials by measuring the absorption of infrared radiation. FTIR is used in pharmaceuticals for drug formulation and quality control, in environmental science for pollutant detection, in food industry for quality assurance, and in materials science for polymer characterization. It is also utilized in forensic analysis, art restoration, and biomedical research. The technique's ability to provide detailed molecular information makes it indispensable for both qualitative and quantitative analysis in diverse applications.
Key Points Explained:
-
Pharmaceuticals:
- Drug Formulation: FTIR is used to analyze the chemical structure of active pharmaceutical ingredients (APIs) and excipients, ensuring the correct formulation of drugs.
- Quality Control: It helps in verifying the purity and consistency of pharmaceutical products, detecting any impurities or deviations from the desired composition.
-
Environmental Science:
- Pollutant Detection: FTIR is employed to identify and quantify pollutants in air, water, and soil samples. It can detect volatile organic compounds (VOCs), greenhouse gases, and other environmental contaminants.
- Monitoring: Continuous monitoring of industrial emissions and environmental samples is possible with FTIR, aiding in compliance with environmental regulations.
-
Food Industry:
- Quality Assurance: FTIR is used to analyze the composition of food products, ensuring they meet safety and quality standards. It can detect adulterants, contaminants, and verify nutritional content.
