| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies sodium phenylpyruvate by titration with standardized HCl using bromocresol green indicator. |
| Water Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Determines trace metal impurities (e.g., Pb, Cd, As) by plasma excitation and elemental emission intensity measurement. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after ignition and drying. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous solution. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase column and UV detection at 254 nm. |
| Loss on Drying | Thermogravimetric Analysis | Measures mass loss upon heating at 105 C for 2 hours under controlled atmosphere. |
| Sodium Content | Flame Photometry | Quantifies sodium by measuring characteristic emission intensity at 589 nm in atomized flame. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference in transmitted daylight. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms and specified pathogens using sterile filtration and selective agar culture. |
