Manufacturing Quality Control of Triphenylene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities by retention time and spectral matching using diode-array detection. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents via gas chromatography with flame ionization detection using headspace sampling. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification using inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after controlled combustion and high-temperature ashing, followed by weighing. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established visual standards under controlled lighting conditions. |
| Solubility in Common Solvents | Qualitative Solubility Test | Observation of complete dissolution or suspension in specified solvents (e.g., toluene, chloroform) at defined temperature and concentration. |
| UV-Vis Absorption Spectrum | UV-Vis Spectrophotometry | Verification of characteristic absorption maxima and spectral profile in solution relative to reference material. |
| Particle Size Distribution | Laser Diffraction | Size analysis based on angular variation of scattered laser light intensity from dispersed particles in liquid medium. |
| Bulk Density | Tap Density Measurement | Determination of mass per unit volume after standardized tapping of a powder sample in a calibrated cylinder. |
