Manufacturing Quality Control of Triphenylethylene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies triphenylethylene content by separation and detection using a capillary column and flame ionization detector. |
| Appearance | Visual Inspection | Assesses physical state and presence of visible particulates or discoloration against standard reference under controlled lighting. |
| Color (APHA) | UV-Vis Spectrophotometry | Measures absorbance at 430 nm in solution and compares to platinum-cobalt color standards. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric titration with iodine generated electrochemically or added stoichiometrically. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metals (e.g., Pb, Cd, Hg, As) by plasma excitation and elemental emission spectroscopy. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies chlorinated by-products based on retention time and mass spectral fragmentation patterns. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated apparatus and standard thermometers. |
| Specific Gravity | Digital Density Meter | Calculates density relative to water at specified temperature using oscillating U-tube principle. |
| Volatile Matter | Thermogravimetric Analysis (TGA) | Quantifies weight loss upon heating under inert atmosphere to determine volatile components. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment and subsequent ignition and weighing. |
