The value-added course on "Integrated use of UV-Vis and FT-IR in pharmaceuticals, Agriculture & Food Tech" was successfully conducted to enhance students' understanding of spectroscopic techniques and their applications in pharmaceuticals, Agriculture & Food Technology.
Key Highlights:
Fundamentals of UV-Vis and FT-IR Spectroscopy
Basic Principles: Interaction of light with matter, absorbance, transmittance, Beer-Lambert Law.
Instrumentation: Components of UV-Vis and FT-IR spectrometers.
Spectral Interpretation: Understanding electronic transitions (UV-Vis) and vibrational modes (FT-IR).
Food Technology
UV-Visible (UV-Vis) and Fourier Transform Infrared (FT-IR) spectroscopy are complementary analytical techniques widely used across pharmaceuticals, agriculture, and food technology for qualitative and quantitative analysis.
Pharmaceuticals
Drug Identification & Purity Testing:
UV-Vis: Measures absorption of active pharmaceutical ingredients (APIs), enabling quantification and concentration analysis.
FT-IR: Identifies functional groups and chemical bonds to confirm drug structure and detect impurities.
Quality Control: Both techniques are used for routine batch analysis and validation of formulations.
Degradation Studies: FT-IR detects chemical changes over time; UV-Vis monitors changes in light absorption due to degradation.
Agriculture
Soil & Plant Analysis:
UV-Vis: Detects nutrient concentrations (e.g., nitrates, phosphates) in soil and water samples.
FT-IR: Assesses organic matter composition, soil texture, and moisture content.
Pesticide Residue Detection: UV-Vis and FT-IR help monitor residual levels on crops, ensuring food safety.
Food Technology
Food Quality & Safety:
UV-Vis: Analyzes color, antioxidant activity, and additives in food products.
FT-IR: Identifies food components such as fats, proteins, and carbohydrates; detects adulterants.
Shelf-life Assessment: Both techniques track changes in food composition and spoilage markers.
Authentication: FT-IR fingerprints are used for origin and authenticity verification of products (e.g., honey, olive oil).
