Manufacturing Quality Control of 1,7-OCTADIYNE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Separation and quantification based on volatility and interaction with column stationary phase. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of sample under controlled conditions followed by weighing of non-volatile residue. |
| Acidity (as Acetic Acid) | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | Visual Comparison (APHA Scale) | Comparison of sample color against platinum-cobalt standard solutions under controlled lighting. |
| Density | Digital Density Meter | Measurement of mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface to infer purity and composition. |
| Flash Point | Closed Cup Tester (e.g., Pensky-Martens) | Measurement of lowest temperature at which vapors ignite momentarily in presence of ignition source. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion by measuring absorption of element-specific wavelengths. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation followed by electron ionization and mass-based identification/quantification of chlorinated compounds. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with sodium thiosulfate. |
| Non-Volatile Matter | Gravimetric Analysis | Filtration and drying of residue after solvent extraction, then weighing of insoluble solids. |
