Manufacturing Quality Control of ETHYLSULFURIC ACID SODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies sodium ethanethiosulfonate by titration with standardized HCl using methyl orange indicator. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance at characteristic wavelengths. |
| Sulfate (SO4) Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after ignition and drying. |
| Chloride (Cl) Impurity | Argentometric Titration | Titrates chloride with standard AgNO3 solution using potassium chromate indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after heating sample at 500-600 C to constant weight. |
| Sodium Content | Flame Photometry | Quantifies sodium by measuring emission intensity at 589 nm in atomized flame. |
| Organic Impurities | High Performance Liquid Chromatography (HPLC) | Separates and quantifies related organic compounds using reverse-phase column and UV detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting. |
| Solubility in Water | Qualitative Solubility Test | Evaluates complete dissolution of specified amount in distilled water at 25 C with gentle agitation. |
| Bulk Density | Volumetric Method | Measures mass per unit volume of freely settled powder in standardized cylinder. |
