Manufacturing Quality Control of 1,5-Pentanedithiol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,5-pentanedithiol peak area relative to calibration standards using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration with iodine generated in situ via reaction with water. |
| Acidity (as H2SO4) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Color | Visual Comparison or Hazen/APHA Color Scale | Compares sample color against platinum-cobalt standard solutions under controlled lighting conditions. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature-controlled measurement. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through the sample at specified temperature to infer composition and purity. |
| Sulfur Content | Combustion IC Analysis (Ion Chromatography) | Oxidizes sulfur to sulfate, then quantifies sulfate ions via suppressed conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomizes sample and measures absorption of characteristic wavelength light by ground-state metal atoms. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume at controlled temperature and pressure, then weighs non-volatile residue. |
| Odor Threshold (Qualitative) | Sensory Evaluation | Trained personnel assess presence/absence of characteristic thiol odor at defined dilution levels. |
| Boiling Range | Distillation (ASTM D1078) | Measures initial and final boiling points using micro-distillation apparatus under reduced pressure if needed. |
| Non-Volatile Matter | Thermogravimetric Analysis (TGA) | Quantifies mass loss upon heating to determine residual inorganic or polymeric contaminants. |
