Manufacturing Quality Control of DOTRIACONTANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies n-dotriacontane peak area relative to internal/external standard using retention time and calibration curve. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Acid Number | Acid-Base Titration with KOH in ethanol | Determines acidic impurities by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color against platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per ASTM D87. |
| Flash Point | Closed Cup Pensky-Martens Tester | Measures lowest temperature at which vapors ignite momentarily when exposed to flame under controlled conditions (ASTM D93). |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of specified sample mass at defined temperature and time. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorption of characteristic atomic spectral lines. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography (IC) | Converts organic sulfur to sulfate via high-temperature combustion; sulfate is quantified by IC conductivity detection. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Detects and quantifies chlorinated hydrocarbons based on molecular ion and fragment patterns after GC separation. |
| Odor | Sensory Evaluation (Trained Panel) | Assesses presence and intensity of off-odor relative to reference standard using standardized organoleptic protocol. |
| Appearance | Visual Inspection | Evaluates physical state, clarity, and presence of particulates or phase separation in a clean, colorless glass container under controlled lighting. |
