Manufacturing Quality Control of Octadecyl isothiocyanate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Number | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., free fatty acids, carbamic acids) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color intensity to platinum-cobalt standard solutions using visual assessment or spectrophotometric absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with the sample. |
| Refractive Index at 20 C | Refractometry (Abbe type) | Determination of refractive index by measuring the critical angle of total internal reflection of light passing through the sample. |
| Residue on Evaporation | Gravimetric Analysis (Hot Plate Evaporation) | Evaporation of a known mass of sample under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Free Isocyanate Content | Dibutylamine Back-Titration | Reaction of isocyanate groups with excess dibutylamine, followed by acid titration of unreacted amine to calculate NCO content. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantitative analysis after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration using silver nitrate solution with silver electrode detection of endpoint via potential change during AgCl precipitation. |
| Viscosity at 25 C | Rotational Viscometry | Measurement of resistance to flow under defined shear rate using a calibrated spindle rotating in the sample. |
| Odor | Sensory Evaluation (Standardized Panel) | Qualitative assessment by trained personnel against reference descriptors and intensity scales per ISO 8586. |
