Manufacturing Quality Control of Hydroxy-PEG3-t-butylester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water and iodine in a methanol-based reagent. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standards using visual matching or spectrophotometric absorbance at 455 nm. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 degrees C using calibrated refractometer. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring atomic absorption at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using conductivity detection after anion exchange separation. |
| Non-Volatile Residue | Evaporation and Gravimetry | Measures residue weight after evaporating known volume at 105 degrees C and drying to constant mass. |
| Peroxide Value | Iodometric Titration | Measures peroxides via oxidation of iodide to iodine, followed by titration with sodium thiosulfate. |
| Appearance | Visual Inspection | Assesses clarity and presence of particulates or phase separation against specified criteria under controlled lighting. |
