| 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 calibrated column and carrier gas. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and gradient elution. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent residues are equilibrated in headspace vial, injected into GC, and quantified against external standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration (NaOH in methanol) | Neutralization of free carboxylic acid groups with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint. |
| Appearance | Visual Inspection | Assessment of liquid clarity and color against water-white standard under controlled lighting and against white background. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
| Refractive Index | Refractometry | Determination of ratio of speed of light in air versus sample at 20 degrees C using calibrated Abbe refractometer. |
| Density | Oscillating U-tube Densitometry | Measurement of sample density via resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element trace metal quantification after microwave-assisted acid digestion and plasma excitation. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation and quantification of chloride anions using anion-exchange column and suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Incineration at 700-800 degrees C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
