Manufacturing Quality Control of 18035-33-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile impurities partitioned into headspace and separated/quantified by GC-FID or GC-MS. |
| Moisture Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water. |
| Acidic Impurities | Acid-Base Titration (with phenolphthalein indicator) | Neutralization of acidic species (e.g., HCl, silanols) with standardized NaOH solution. |
| Chloride Ion Content | Potentiometric Titration with AgNO3 | Precipitation of Cl- as AgCl monitored by silver ion-selective electrode endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Multi-element quantification after acid digestion based on element-specific atomic emission intensities. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Residue mass measured after evaporation of sample under controlled temperature and vacuum. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co scale) | Comparison of sample solution color intensity against platinum-cobalt standard solutions. |
| Density | Digital Density Meter (Oscillating U-tube) | Measures density via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Determines refractive index from critical angle of total internal reflection at prism-sample interface. |
| Silanol Content | 1H NMR Spectroscopy | Quantifies Si-OH protons (delta ~1.5–2.5 ppm) relative to reference compound or integral of aromatic protons. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measures weight loss as function of temperature under inert atmosphere to assess decomposition onset. |
