Manufacturing Quality Control of 1-ETHYLNAPHTHALENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | 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 Number | Acid-Base Titration (NaOH in ethanol) | Neutralization of acidic impurities by standardized sodium hydroxide solution, using phenolphthalein indicator or potentiometric endpoint. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Measurement of yellowness intensity by comparing sample absorbance at 455 nm to platinum-cobalt standard solutions. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass under controlled conditions followed by weighing of non-volatile residue. |
| Non-Volatile Matter | Gravimetric Analysis | Same principle as residue on evaporation; measures total insoluble and non-volatile contaminants after solvent removal. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities via absorption of characteristic wavelength light by ground-state atoms in a flame or graphite furnace. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography (IC) | Complete combustion converts sulfur compounds to sulfate, which is then separated and quantified by conductivity detection. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by identification and quantification of chlorinated by-products using mass spectral fragmentation patterns. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface at 20 degrees C using calibrated Abbe refractometer. |
| Density | Digital Density Meter (Oscillating U-tube) | Determination based on resonant frequency shift of a U-shaped tube filled with sample at controlled temperature. |
| Boiling Range | Gas Chromatography (GC) or Distillation Apparatus | GC method: retention time window relative to standards; Distillation: ASTM D1078 procedure measuring initial and final boiling points under reduced pressure. |
