Manufacturing Quality Control of di-p-tolyl sulphide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies di-p-tolyl sulphide peak area relative to internal/external standard using retention time and calibration curve. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing and subsequent weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Sulphated Ash | Gravimetric Analysis | Determines inorganic sulphate residue after combustion with sulphuric acid followed by ignition and weighing. |
| Color (APHA) | Visual Comparison or Spectrophotometry (430 nm) | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt standard solutions or measuring absorbance. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at 20 degC to assess purity and composition. |
| Specific Gravity | Pycnometry or Digital Density Meter | Compares density of sample to water at specified temperature using calibrated volume or oscillating U-tube principle. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies low-boiling organic impurities based on retention time and mass spectral fragmentation. |
| Non-Volatile Residue | Evaporation and Gravimetry | Determines residue after controlled evaporation of a fixed sample volume under nitrogen and drying to constant weight. |
| Odor | Sensory Evaluation (Qualified Personnel) | Assesses presence of off-odor indicative of degradation or contamination by trained personnel under standardized conditions. |
