Manufacturing Quality Control of beta-Bromostyrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies bromo-camphene content by retention time and peak area comparison against a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual solids. |
| Acid Value | Acid-Base Titration | Quantifies free acidic impurities by titration with standardized KOH solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through the sample at specified temperature using calibrated Abbe refractometer. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring atomic absorption of characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Non-Volatile Residue | Evaporation and Gravimetry | Determines residue after gentle evaporation of a fixed sample volume under controlled conditions and subsequent weighing. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral molecules in solution using sodium D-line. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Identifies and quantifies volatile organic solvents by analyzing vapor phase above equilibrated sample. |
