Manufacturing Quality Control of N-OCTADECYLDIMETHYLMETHOXYSILANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component by separation and peak area comparison against reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration | Determines free acid content by titration with standardized KOH solution using phenolphthalein indicator. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 C to assess purity and consistency. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by matching sample color to APHA platinum-cobalt scale standards. |
| Chloride Content | Potentiometric Titration with AgNO3 | Quantifies chloride ions by argentometric titration using silver nitrate and silver electrode detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Volatile Matter | Thermogravimetric Analysis (TGA) | Determines weight loss upon controlled heating to quantify low-boiling impurities. |
| Viscosity | Rotational Viscometry | Measures resistance to flow under shear stress at controlled temperature using spindle method. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of ground-state atoms in flame. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determines lowest temperature at which vapors ignite momentarily under standardized closed-cup conditions. |
