Manufacturing Quality Control of propyl benzenesulphonate
| 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 using a non-polar capillary column. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of free acidic impurities by standardized sodium hydroxide solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical determination of water via iodine generation and stoichiometric reaction with water in anhydrous methanol medium. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity against platinum-cobalt standards or measurement of absorbance at 455 nm in a 10-mm cell. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 C | Abbe Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of a weighed sample under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantification of total heavy metals after acid digestion, using air-acetylene flame AAS with appropriate calibration standards. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation and quantification of chloride ions on an anion-exchange column with suppressed conductivity detection. |
| Non-Volatile Matter | Gravimetric Analysis (Hot Plate Evaporation) | Evaporation of a known volume on a pre-weighed dish at 105 C to constant weight, then weighing residual solids. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution in a defined path length cell at specified temperature and wavelength. |
| Volatile Organic Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Extraction and identification of low-boiling impurities via equilibrium headspace sampling followed by GC separation and MS detection. |
