Manufacturing Quality Control of Isopropyl Benzenesulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluation of yellowish tint by matching sample color to APHA platinum-cobalt standards or measuring absorbance at 455 nm. |
| 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 | Abbe Refractometer | Determination of light bending angle at air-sample interface to infer molecular composition and purity. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass to dryness followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion, based on absorption of element-specific hollow cathode lamp radiation. |
| Chloride Impurity | Ion Chromatography (IC) or Potentiometric Titration | Separation and quantification of chloride ions using ion-exchange column and conductivity detection, or titration with silver nitrate. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitation of sulfate as BaSO4 in acidic medium followed by filtration, drying, and weighing. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporation of sample under controlled temperature and pressure, then weighing residual solids. |
| Odor | Sensory Evaluation | Subjective assessment by trained personnel against specification for characteristic ester-like odor; absence of off-odors. |
