Manufacturing Quality Control of Phthalan
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine-methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Color | Visual Comparison or Hazen Color Scale | Compares sample color to platinum-cobalt standard solutions under controlled lighting conditions. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement. |
| Boiling Point Range | Distillation Apparatus (ASTM D86) | Measures initial and final boiling points under atmospheric pressure using standardized distillation setup. |
| Non-Volatile Residue | Evaporation and Gravimetry | Quantifies residue after solvent evaporation under controlled temperature and vacuum. |
| Heavy Metals (as Pb) | ICP-OES | Detects trace metal elements by plasma-induced atomic emission spectroscopy after acid digestion. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via silver nitrate titration monitored by silver ion-selective electrode. |
| Specific Optical Rotation | Polarimetry | Determines rotation of plane-polarized light caused by chiral molecules in solution. |
