Manufacturing Quality Control of LIGHT GREEN SF YELLOWISH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~620 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent; based on stoichiometric reaction of water with iodine and sulfur dioxide. |
| Heavy Metals (as Pb) | ICP-OES | Simultaneously detects trace metal impurities after acid digestion by measuring element-specific emission intensities in argon plasma. |
| Chloride Impurity | Potentiometric Titration | Uses silver nitrate titrant with chloride-selective electrode to detect endpoint based on change in electrode potential. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as barium sulfate under controlled conditions and determines mass after drying and weighing. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and cooling in desiccator. |
| pH of Aqueous Solution | pH Meter Measurement | Determines hydrogen ion activity in a defined aqueous suspension (e.g., 1% w/v) using calibrated glass electrode system. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase column and UV detection, relative to main peak area. |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Atomizes sample in air-acetylene flame and measures absorption of iron-specific wavelength (248.3 nm). |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity pattern to calculate size distribution based on Mie theory. |
| Bulk Density | Weight/Volume Method | Determines mass per unit volume (g/mL) of freely settled powder in standardized cylinder under controlled conditions. |
| Solubility in Water | Visual Observation & Filtration | Evaluates complete dissolution of specified amount in distilled water at 25 C with gentle agitation, followed by visual inspection and filtration check. |
