| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) by atomic emission spectroscopy after acid digestion. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Specific Optical Rotation | Polarimetry | Measures optical activity using plane-polarized light to assess chiral purity and identity. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample at specified temperature using critical angle principle. |
| Density | Oscillating U-tube Densitometry | Measures mass per unit volume via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents by equilibrium partitioning into headspace followed by GC analysis. |
| pH (10% w/v aqueous solution) | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in aqueous dilution. |
