Manufacturing Quality Control of 1833-51-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component using retention time and peak area against calibrated standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| Acidity (as HCl) | Acid-Base Titration | Determines acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing. |
| Chloride Content | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant and silver/silver chloride electrode detection. |
| Density | Pycnometry | Determines mass per unit volume at specified temperature using calibrated glass pycnometer. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 C using calibrated refractometer. |
| Boiling Point Range | Distillation (ASTM D1078) | Determines temperature range over which 90% of sample distills under reduced pressure. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace heavy metals via absorption of element-specific hollow cathode lamp radiation. |
| Non-Volatile Matter | Evaporation and Weighing | Measures residue after controlled evaporation of known sample mass under inert atmosphere. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness intensity by matching to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Peroxide Value | Iodometric Titration | Detects peroxides by oxidation of iodide to iodine, followed by titration with standardized sodium thiosulfate. |
