Manufacturing Quality Control of 4-Pentylbromobenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatiles are thermally extracted into headspace and separated/quantified via GC-FID or GC-MS. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration (NaOH in methanol/water) | Neutralization of acidic impurities (e.g., HBr, brominated acids) with standardized alkali; phenolphthalein or potentiometric endpoint. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES after acid digestion | Sample digested in nitric/hydrochloric acid; elemental concentrations measured by plasma ionization and mass/optical emission detection. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation & Weighing) | Sample evaporated to dryness at 105 °C; residue weighed to determine inorganic/organic non-volatile contaminants. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement (430 nm) | Compares sample color intensity against platinum-cobalt standard scale; quantified via absorbance at 430 nm. |
| Refractive Index | Refractometry (20 °C) | Measures bending of light through liquid sample at controlled temperature; correlates with purity and composition. |
| Density | Digital Density Meter (Oscillating U-tube, 20 °C) | Determines mass per unit volume via resonant frequency shift of oscillating U-tube filled with sample. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separates chloride anions on ion-exchange column; quantified by conductivity response relative to calibration standards. |
