| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies辛酸糠酯 peak area relative to internal/external standard using retention time and calibration curve. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric reaction between water and iodine in a specialized reagent. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content via neutralization with standardized sodium hydroxide solution. |
| Ester Value | Saponification followed by Acid-Base Titration | Measures total ester content by alkaline hydrolysis and back-titration of excess alkali. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample at specified temperature using calibrated refractometer. |
| Specific Gravity | Digital Density Meter or Pycnometer | Compares mass of fixed volume of sample to equivalent volume of water at standard temperature. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA Scale | Evaluates yellowness intensity by matching sample color to platinum-cobalt standard solutions. |
| Residue on Ignition | Gravimetric Analysis after Muffle Furnace Heating | Measures non-volatile inorganic impurities remaining after high-temperature ashing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal content by measuring absorption of element-specific wavelength light in atomized sample. |
| Residual Solvents (e.g., ethanol, toluene) | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents using equilibrium vapor phase analysis. |
| Peroxide Value | Iodometric Titration | Measures hydroperoxides by oxidation of iodide to iodine, followed by thiosulfate titration. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of suspended particles or phase separation under controlled lighting. |
