| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by separation and flame ionization detection relative to internal/external standard. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents based on partitioning into headspace and GC separation. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemically determines water via iodine generation and stoichiometric reaction with water. |
| Acid Value | Acid-Base Titration (NaOH in methanol) | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES after acid digestion | Quantifies trace metals following microwave-assisted nitric/hydrogen peroxide digestion and plasma-based elemental detection. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after controlled high-temperature ashing at 500–600 °C. |
| Optical Rotation | [α]D Measurement (Polarimetry) | Determines specific rotation using sodium D-line light to assess chiral purity and absence of racemization. |
| Appearance & Color | Visual Inspection & Hazen (APHA) Color Scale | Evaluates clarity and yellowness by visual comparison against platinum-cobalt standards in a 100-mm cell. |
| Density | Digital Density Meter (Oscillating U-tube) | Measures mass per unit volume at specified temperature via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
