| 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 under specified chromatographic conditions. |
| Specific Optical Rotation | [a]D at 20 C | Measurement of rotation angle of plane-polarized light passing through a solution, used to confirm enantiomeric identity and purity. |
| Refractive Index | Refractometry at 20 C | Determination of ratio of speed of light in air vs. sample, correlated with purity and composition. |
| Density | Digital densitometry at 20 C | Mass per unit volume measurement using oscillating U-tube principle for compositional verification. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric analysis after ashing | Weight of non-volatile residue remaining after high-temperature incineration, indicating inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantification of metals (e.g., Pb, Cd, Hg, As) by measuring absorption of characteristic wavelengths of light by ground-state atoms. |
| Acid Value | Acid-base titration with NaOH | Neutralization of free acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual or spectrophotometric comparison | Evaluation of yellowness intensity relative to platinum-cobalt standards using APHA scale. |
| Non-Volatile Matter | Gravimetric evaporation | Weight of residue after controlled evaporation of a known sample mass under specified temperature and time. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Separation and quantification of volatile organic solvents using headspace sampling and GC-FID. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and semi-quantification of structurally related impurities based on retention time and mass spectral matching. |
