Manufacturing Quality Control of 18724-32-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard under optimized chromatographic conditions. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities are quantified by equilibrium partitioning into headspace and separation on a polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Acid Number | Acid-Base Potentiometric Titration | Neutralization of acidic impurities with standardized KOH solution; equivalence point determined from pH inflection. |
| Viscosity | Capillary Viscometry (ASTM D445) | Measures kinematic viscosity by timing gravitational flow of sample through a calibrated glass capillary tube at controlled temperature. |
| Density | Digital Density Meter (Oscillating U-tube, ASTM D4052) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Abbe Refractometer (ASTM D1218) | Measures refractive index based on critical angle of total internal reflection at the prism-sample interface. |
| Color | Gardner Color Scale (ASTM D1500) | Visual or instrumental comparison of sample color against standardized colored glass discs or digital calibration. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection via atomic emission from plasma-excited sample aerosol; quantification using calibration curves. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride anions on anion-exchange column followed by quantitative detection via conductivity measurement. |
| Non-Volatile Residue | Gravimetric Analysis (Hot Plate Evaporation) | Sample evaporated to dryness under controlled heating; residue weighed after cooling in desiccator. |
| Stereoisomer Ratio | Chiral Gas Chromatography (Chiral GC) | Enantiomeric or diastereomeric separation using chiral stationary phase; ratio calculated from relative peak areas. |
