| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separates and quantifies volatile organic solvents based on retention time and peak area against reference standards. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) | Atomizes sample and measures element-specific emission intensities at characteristic wavelengths. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions using visual assessment or absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Measures density based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry | Determines refractive index by measuring angle of light refraction at air-sample interface using calibrated prism. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates and identifies low-level volatile impurities via retention time and mass spectral fragmentation patterns. |
| Sulfated Ash | Gravimetric Analysis after Ignition | Measures inorganic residue remaining after high-temperature combustion and sulfuric acid treatment. |
| pH (10% w/w aqueous solution) | pH Meter with Combination Electrode | Measures hydrogen ion activity in aqueous dispersion using calibrated glass/reference electrode system. |
