Manufacturing Quality Control of PRISTANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies姥鲛烷 peak area against a calibrated standard curve using capillary column separation. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol medium. |
| Acid Value | Acid-Base Titration with KOH ethanol solution | Determines free carboxylic acids by titration with standardized potassium hydroxide solution in ethanol. |
| Peroxide Value | Iodometric Titration | Measures peroxides by oxidation of iodide to iodine, followed by titration with standardized sodium thiosulfate. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color to APHA platinum-cobalt standards or measures absorbance at 430 nm in a 10 mm cell. |
| Refractive Index | Refractometry at 20 C | Determines refractive index using a calibrated Abbe refractometer at controlled temperature. |
| Specific Gravity | Pycnometry or Digital Density Meter | Measures mass-to-volume ratio relative to water at specified temperature using calibrated glass pycnometer or oscillating U-tube densitometer. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates a known mass of sample under controlled conditions and weighs non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantifies total heavy metals after acid digestion by measuring atomic absorption of lead-specific wavelength. |
| Sulfated Ash | Gravimetric Analysis after sulfuric acid treatment | Measures inorganic residue after charring, sulfuric acid treatment, and high-temperature incineration. |
| Non-Volatile Matter | Gravimetric Analysis | Determines residue after evaporation of a fixed sample mass under defined temperature and time conditions. |
| Odor | Sensory Evaluation by Trained Panel | Assesses off-odor presence and intensity against reference standards using standardized organoleptic testing protocol. |
