| 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 non-polar capillary column. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities are equilibrated in headspace vial and quantified by GC-FID or GC-MS against calibration standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Sample digested in acid matrix; metal concentrations determined by element-specific atomic emission intensities. |
| Iodide Ion Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column; iodide quantified by conductivity response relative to calibration curve. |
| Acid Value | Acid-Base Titration (NaOH in ethanol) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity against APHA platinum-cobalt standard scale or absorbance measurement at specified wavelength. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated to 600-700 C in platinum crucible; residue weight measured after cooling in desiccator. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as temperature range at which solid phase changes to liquid under controlled heating rate. |
| Organic Volatile Impurities (OVI) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and quantification of unknown volatile organic impurities via retention time and mass spectral matching. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and path length. |
