Manufacturing Quality Control of 13528-93-3
| 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 | Gas Chromatography (GC) with Headspace sampling | Volatile impurities are partitioned into headspace and quantified using calibrated external standards. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Number | Acid-Base Potentiometric Titration | Neutralization of acidic impurities with standardized KOH solution; endpoint detected by pH electrode. |
| Chloride Ion Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on ion-exchange column followed by quantitative detection via conductivity. |
| Heavy Metals (Pb, Cd, Cr, Hg, As) | ICP-MS | Multi-element detection after acid digestion; isotopic measurement provides ultratrace sensitivity and specificity. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Sample evaporated to dryness at controlled temperature; residue mass measured as percentage of initial sample weight. |
| Color | Visual Comparison or Spectrophotometric Measurement (APHA/Pt-Co Scale) | Comparison of sample color against platinum-cobalt standard solutions using visual assessment or absorbance at 455 nm. |
| Density | Oscillating U-tube Densitometry | Measurement of resonant frequency shift of a vibrating U-shaped tube filled with sample, correlated to density. |
| Refractive Index | Digital Refractometry | Determination of refractive index at specified temperature using total internal reflection principle. |
| Volatility Loss (105 C, 2 h) | Thermogravimetric Analysis (TGA) | Mass loss measured during isothermal heating at 105 C for 2 hours under inert atmosphere. |
| Trace Siloxane Impurities | GC-MS | Separation by GC followed by identification and quantification of cyclic/linear siloxanes using mass spectral libraries and selected ion monitoring. |
