Manufacturing Quality Control of Diphenylacetylene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component by separation and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in a coulometric or volumetric titration system. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual residue. |
| Heavy Metals | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) using element-specific atomic emission lines. |
| Chloride Content | Potentiometric Titration with Silver Nitrate | Detects chloride ions by titration with AgNO3 and endpoint determination using silver ion-selective electrode. |
| Acid Value | Acid-Base Titration | Measures acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Determines purity and identity by observing temperature range at which solid transitions to liquid under controlled heating. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against specified criteria. |
| Solubility | Qualitative Solubility Test | Evaluates complete dissolution behavior in specified solvents (e.g., toluene, acetone) at defined temperature and concentration. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling residual solvents by analyzing vapor phase above sample at equilibrium temperature. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after combustion with sulfuric acid pretreatment and subsequent ignition. |
