Manufacturing Quality Control of ETHANE SULFINIC ACID SODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NaC2H5SO2) | Acid-Base Titration with HCl | Quantifies active ingredient by back-titration after acid hydrolysis to liberate SO2, followed by iodometric determination. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and Karl Fischer reagent. |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated pH electrode in standardized aqueous suspension. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths. |
| Sulfate (SO4) | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after ignition and drying. |
| Chloride (Cl) | Argentometric Titration (Mohr method) | Titrates chloride with standard AgNO3 solution using K2CrO4 indicator for endpoint detection. |
| Iron (Fe) | ICP-OES | Measures iron concentration by plasma excitation and emission intensity at specific spectral lines. |
| Sodium (Na) | Flame Photometry | Quantifies sodium based on emission intensity of excited Na atoms in flame. |
| Organic Impurities | HPLC-UV | Separates and quantifies organic impurities using reversed-phase chromatography and UV absorbance detection. |
| Residue on Ignition | Gravimetric Weight Loss | Measures non-volatile inorganic residue after high-temperature ashing at 500-600 C. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume after controlled tapping of a known mass in a graduated cylinder. |
