Manufacturing Quality Control of Diphenylsilanediol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component by separation and detection based on volatility and polarity differences. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized KOH solution using phenolphthalein indicator. |
| Hydroxyl Value | Acetic Anhydride Acylation Titration | Quantifies total hydroxyl groups via acylation followed by back-titration of unreacted anhydride. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects trace metal contaminants by measuring absorption of characteristic wavelengths of light. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies iron by plasma-induced atomic emission at element-specific wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions via precipitation titration monitored by silver ion-selective electrode. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting. |
| Density | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle at specified temperature. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Identifies and quantifies low-boiling impurities by analyzing vapor phase above heated sample. |
