|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and base in methanol to quantify water via stoichiometric reaction. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., HBr) using standardized sodium hydroxide solution and potentiometric or indicator endpoint detection. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a measured sample under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color to APHA platinum-cobalt standard solutions using visual assessment or absorbance measurement at 455 nm. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer or digital equivalent. |
| Boiling Range | Distillation with ASTM D86 Apparatus | Fractional distillation under atmospheric pressure to determine initial and final boiling points of the main component. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of acid-digested sample followed by measurement of absorbance at characteristic wavelength for lead. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of specified sample volume to dryness at 105 C, followed by cooling and precise weighing of residue. |
| Stability (Thermal Decomposition Onset) | Thermogravimetric Analysis (TGA) | Monitoring of mass loss as a function of temperature under inert atmosphere to determine onset decomposition temperature. |
