Manufacturing Quality Control of Fluorexon
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~438 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal content after wet digestion by measuring atomic absorption of vaporized metal atoms in flame or graphite furnace. |
| Loss on Drying (LOD) | Gravimetric Analysis (Thermogravimetry) | Determines volatile content by measuring mass loss after heating sample at 105 C for 2 hours under controlled conditions. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Measures inorganic impurities by igniting residue after sulfuric acid treatment and weighing the non-volatile ash. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Quantifies chloride ions via argentometric titration using silver nitrate and a silver indicator electrode. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4, filters, dries, and weighs to determine sulfate content. |
| Iron (Fe) Content | ICP-OES | Detects and quantifies iron after acid digestion by measuring element-specific emission intensities in high-temperature plasma. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode and pH meter. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser light passing through dispersed sample. |
| Melting Point | Capillary Melting Point Apparatus | Identifies temperature range at which solid transitions to liquid, indicating purity and identity. |
| Water Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol medium. |
