Manufacturing Quality Control of Tetraoctylammonium bromide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Water Content | Karl Fischer titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric analysis | Mass of non-volatile inorganic residue measured after high-temperature ashing at 700-800 C. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification by measuring atomic emission intensities of metal ions in plasma-excited sample aerosol. |
| Chloride Impurity | Potentiometric titration with AgNO3 | Titration based on formation of insoluble AgCl, detected by silver electrode potential change. |
| Bromide Content | Ion Chromatography (IC) | Separation and quantification of bromide anions using anion-exchange column and conductivity detection. |
| Melting Point | Capillary melting point apparatus | Thermal transition observed visually as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting. |
| Solubility in Water | Qualitative dissolution test | Observation of complete dissolution in specified volume of water at 25 C with gentle agitation. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents via gas chromatography with flame ionization detection. |
| pH of Aqueous Solution (1% w/v) | pH meter measurement | Electrochemical determination of hydrogen ion activity in a standardized aqueous solution. |
| Bulk Density | Graduated cylinder method | Mass per unit volume measured by tapping a known mass in a calibrated cylinder to determine settled volume. |
