Manufacturing Quality Control of methoxyacetic anhydride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Acidity (as Acetic Acid) | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | Visual Comparison or Hazen (APHA) Scale | Comparison of sample color against platinum-cobalt standard solutions under controlled lighting conditions. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using Abbe refractometer or digital equivalent. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after controlled high-temperature ashing in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal content by measuring absorption of characteristic wavelength light after acid digestion and atomization. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride anions on an anion-exchange column with conductivity detection. |
| Residual Solvents | Gas Chromatography (GC) with FID | Identification and quantification of volatile organic solvents using headspace or direct injection with polar capillary column. |
| Appearance | Visual Inspection | Assessment of clarity and presence of suspended particles or phase separation in a transparent container under daylight-equivalent illumination. |
| Boiling Point Range | Distillation (Micro or Semi-micro) | Determination of temperature interval over which the majority of sample distills under controlled atmospheric pressure. |
