Manufacturing Quality Control of o-Terphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies main component by separation and flame ionization detection relative to calibrated standards. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by high-temperature ashing and weighing of residual mass. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metals (e.g., Pb, Cd, Hg) by measuring absorption of specific wavelengths of light by ground-state atoms in flame or graphite furnace. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies chlorinated aromatic impurities based on retention time and characteristic mass fragmentation patterns. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Acid Value | Acid-Base Titration with NaOH | Measures free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry (430 nm) | Evaluates yellowness intensity by comparing sample color to APHA platinum-cobalt standard solutions. |
| Non-Volatile Residue | Evaporation and Gravimetry | Determines volatile loss by evaporating sample under controlled conditions and weighing residue. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic sulfate content after combustion with sulfuric acid treatment and high-temperature ignition. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at specified temperature using oscillating U-tube principle. |
| Organic Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling residual solvents by analyzing vapor phase above heated sample using GC-FID. |
