| Materials Science | Modifier for polymeric materials | Copolymerization and grafting reactions |
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities under natural or standard lighting conditions. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column and a UV detector (e.g., 254 nm). Qualitative analysis is based on retention time, and quantitative analysis is performed using peak area normalization or external standard method. |
| Content Determination | Gas Chromatography (GC) or HPLC | GC is suitable for volatile samples using an FID detector; HPLC is more commonly used for polar compounds, with quantitative analysis based on reference standards. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | ¹H-NMR and ¹³C-NMR are used to confirm molecular structure by comparing characteristic peak positions with literature data. |
| Structure Confirmation | Mass Spectrometry (MS) | Utilizes EI or ESI ionization to detect molecular ion peaks ([M+H]+), aiding in the determination of molecular weight and fragment structures. |
| Residual Solvents | Gas Chromatography (GC) | Detects organic solvents (e.g., methanol, ethanol, acetone) that may remain from the manufacturing process, in accordance with pharmacopoeia standards (e.g., Chinese Pharmacopoeia, USP). |
| Moisture Content | Karl Fischer Titration | Accurately determines moisture content using titration, available as volumetric or coulometric methods, suitable for trace moisture analysis. |
| Melting Point | Melting Point Apparatus | Measures the initial and final melting temperatures of a compound using an automated or capillary melting point apparatus to assess purity and consistency. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detects heavy metal residues such as lead, cadmium, mercury, and arsenic. Samples must undergo digestion and results must comply with pharmaceutical or industrial standard limits. |
| Microbial Limits | Microbial Culture Method | Tests for total aerobic microbial count, total yeast and mold count, and specified microorganisms (e.g., Escherichia coli, Salmonella) according to pharmacopoeia standards, applicable for pharmaceutical-grade products. |
