Manufacturing Quality Control of 1,2-Diphenylethane
| 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. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color to APHA platinum-cobalt standards or measurement of absorbance at 455 nm in a 10 cm cell. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 C | Refractometry (Abbe type) | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporation of a known mass of sample under controlled conditions followed by weighing of residual matter. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Quantification of total heavy metals after microwave-assisted nitric acid digestion, measured by flame or graphite furnace AAS. |
| Residual Solvents (e.g., benzene, toluene) | Headspace Gas Chromatography (HS-GC) with FID | Extraction of volatile organics into headspace gas, followed by GC separation and FID detection. |
| Chlorinated Impurities (e.g., chlorobenzene) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC and identification/quantification of chlorinated compounds using electron ionization and selected ion monitoring. |
| Odor | Sensory Evaluation (Standardized Panel) | Assessment by trained personnel against defined odor descriptors and intensity scales per ISO 8586. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-liquid phase transition temperature using controlled heating and optical observation of meniscus movement. |
