Mass Spectrometry (MS): This technique helps in identifying the molecular weight and structure of degradation products. Chromatography: Techniques like HPLC (High-Performance Liquid Chromatography) and GC (Gas Chromatography) are used to separate and analyze complex mixtures of degradation products. Spectroscopy: Methods like FTIR (Fourier Transform Infrared Spectroscopy) and NMR (Nuclear Magnetic Resonance) provide detailed information about the chemical structure of degradation products.
