| Chemical Manufacturing | Preservative or stabilizer | Additive blending |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanolic buffer. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing of residue. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co scale) | Evaluates color intensity by comparison to platinum-cobalt standard solutions or absorbance at 455 nm. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 C to assess purity and concentration. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of ground-state atoms in flame. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration monitored by silver electrode potential change. |
| Non-Volatile Residue | Evaporation and Gravimetry | Measures residue mass after evaporation of fixed sample volume under controlled conditions. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of suspended particles or phase separation in container. |
| Odor | Sensory Evaluation | Evaluates characteristic odor profile for off-odor or degradation indicators per established sensory protocol. |
