Manufacturing Quality Control of 6245-59-6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at lambda-max (approx. 510 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomizes sample and measures absorption of characteristic wavelength light by ground-state metal atoms in flame or graphite furnace. |
| Sulfated Ash | Gravimetric Analysis | Ignites sample at 750-800 C in platinum crucible, then weighs residual inorganic ash after acid treatment and drying. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects endpoint via potential change during precipitation of AgCl using silver nitrate titrant and silver indicator electrode. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in aqueous dispersion using calibrated glass electrode and reference electrode. |
| Organic Impurities (Related Substances) | High Performance Liquid Chromatography (HPLC) | Separates components on reversed-phase column and detects impurities by UV absorbance relative to main peak. |
| Iron (Fe) Content | ICP-OES | Atomizes and excites sample in argon plasma; quantifies Fe by measuring intensity of characteristic emission line. |
| Filterability | Gravity Filtration Test | Evaluates suspension clarity and particulate content by filtering standardized solution through specified membrane and timing flow. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely settled powder poured into calibrated cylinder under controlled conditions. |
| Particle Size Distribution | Laser Diffraction | Analyzes angular scattering pattern of laser beam passed through dispersed particles to calculate size distribution. |
| Water Solubility | Visual Dissolution Test | Determines completeness of dissolution in distilled water at 25 C by visual inspection after defined agitation and settling time. |
