Manufacturing Quality Control of 7691-02-3
| 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. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine consumption in pyridine-methanol solvent system. |
| Acid Number | Acid-Base Titration with NaOH standard solution | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measures sample density from resonant frequency shift of vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Abbe Refractometer | Determines refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA Scale | Evaluates yellowness by matching sample color to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Measures non-volatile residue after controlled evaporation and drying under specified temperature and vacuum. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in plasma; quantifies metal emissions at characteristic wavelengths. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Extracts and separates volatile components from headspace vapor, identified and quantified by mass spectral libraries. |
| Viscosity at 25 C | Rotational Viscometer (e.g., Brookfield) | Measures resistance to flow under controlled shear rate using rotating spindle immersed in sample. |
| pH of Aqueous Solution (10% w/w) | pH Meter with Combination Electrode | Determines hydrogen ion activity in aqueous dilution using calibrated glass/ reference electrode system. |
