| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in anhydrous methanol-based solvent. |
| Residue on Ignition | Gravimetric Analysis | Mass loss after high-temperature ashing (550-600 C) followed by weighing of inorganic residue. |
| Chloride Impurities (e.g., HCl, Cl2) | Ion Chromatography (IC) | Separation and quantification of ionic chlorides using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelength. |
| Sulfur Content | Combustion IC (or UV Fluorescence Detection) | Oxidative combustion to SO2 followed by quantitative detection via UV fluorescence or ion chromatography. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual sulfonic acids) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Solubility in Common Solvents | Qualitative Solubility Test | Observation of complete dissolution in specified solvents (e.g., chloroform, toluene) at room temperature. |
| Volatile Organic Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identification and semi-quantification of low-boiling impurities via thermal desorption and mass spectral detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using angular scattering pattern of laser light to calculate size distribution. |
