Manufacturing Quality Control of Rubrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies red fluorescent content using reversed-phase HPLC with UV detection at characteristic absorbance wavelength. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents by gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Measures trace metal impurities (e.g., Pb, Cd, Hg) via inductively coupled plasma mass spectrometry for high sensitivity. |
| Chlorinated Impurities | GC-ECD | Identifies and quantifies chlorinated organic impurities using electron capture detection in gas chromatography. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature combustion and subsequent weighing of the remaining ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid red fluorescent transitions to liquid phase using calibrated capillary method. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular variation of scattered laser light. |
| Organic Volatile Impurities | Headspace GC-MS | Detects low-level volatile organic impurities via headspace sampling followed by gas chromatography-mass spectrometry. |
| Sulfated Ash | Gravimetric Analysis | Quantifies residual inorganic sulfate after sulfuric acid treatment and high-temperature ignition. |
| Related Substances | HPLC-DAD | Identifies and quantifies structurally related impurities using high-performance liquid chromatography with diode array detection. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of powder after standardized tapping to assess flow and packing behavior. |
