Manufacturing Quality Control of 1,2,3,4-TETRAHYDRO-1,1,4,4-TETRAMETHYLNAPHTHALENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and quantifies impurities based on relative response factors and retention behavior. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous medium. |
| Acid Value | Acid-Base Titration (NaOH in ethanol/isopropanol) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample color intensity to platinum-cobalt standard scale or measures absorbance at specified wavelength. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube principle) | Measures sample density via frequency shift of vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Refractometry (Abbe type) | Determines refractive index by measuring critical angle of total internal reflection. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporates sample under controlled conditions and weighs residual non-volatile material. |
| Residue on Ignition | Gravimetric Analysis (High-Temperature Ashing) | Ignites residue from non-volatile test at 700-800 degC and weighs inorganic ash content. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and detects chloride ions via conductivity detection or silver nitrate titration with endpoint detection. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under standardized conditions. |
