Manufacturing Quality Control of 1-Ethynyl-4-pentylbenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration standard using flame ionization detection. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by analyzing vapor phase above sample at controlled temperature. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemically determines water via iodine generation and stoichiometric reaction with water. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies trace metals after acid digestion by measuring element-specific atomic emission intensities. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Determines residue mass after evaporation of sample under controlled temperature and vacuum. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color intensity against platinum-cobalt standard solutions in the visible range. |
| Refractive Index | Refractometry at 20 degrees C | Measures bending of light through liquid sample to determine purity and composition. |
| Density | Oscillating U-tube Densitometry | Determines mass per unit volume from resonant frequency of a vibrating sample-filled tube. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions using anion-exchange column and conductivity measurement. |
| Peroxide Value | Iodometric Titration | Measures peroxides by iodide oxidation to iodine, followed by titration with standardized sodium thiosulfate. |
