| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 500-600 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion, using lead as the representative element and air-acetylene flame. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride anions on an anion-exchange column with suppressed conductivity detection. |
| Aldehyde Content (Total) | UV-Vis Spectrophotometry (with Nash reagent) | Colorimetric reaction of aldehydes with acetylacetone and ammonium acetate to form a yellow dihydropyridine derivative measured at 412 nm. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities (e.g., glycolaldehyde monomer, glyoxal, ethylene glycol) on a reversed-phase C18 column. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against water-white standard under controlled lighting conditions. |
| Specific Gravity | Digital Density Meter | Measurement of density at 20 C relative to water using oscillating U-tube principle. |
