Manufacturing Quality Control of Disodium methanedisulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl solution using bromocresol green indicator. |
| Water Content | Karl Fischer Titration | Measures water via iodometric reaction where water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Sodium Content | ICP-OES | Determines sodium concentration by measuring characteristic atomic emission intensity after plasma atomization and excitation. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate anions using anion-exchange column and suppressed conductivity detection. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Measures chloride via argentometric titration using silver nitrate and a silver/silver chloride electrode. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantifies total heavy metals by atomic absorption of ground-state atoms in flame or graphite furnace. |
| pH (1% aqueous solution) | pH Meter Measurement | Determines hydrogen ion activity in aqueous solution using calibrated glass electrode system. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Organic Impurities | HPLC-UV | Separates and detects organic impurities using reversed-phase chromatography and UV absorbance detection at 210-254 nm. |
| Iron Content | AAS | Quantifies iron by measuring absorption of specific wavelength light by free iron atoms in flame. |
| Appearance (Color and Clarity) | Visual Inspection | Assesses physical state, color, and clarity against standard white background under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles by analyzing angular variation in laser light scattering intensity. |
