Manufacturing Quality Control of Triphenylphosphine-3,3',3''-trisulfonic acid trisodium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (PPh3 core content) | HPLC-UV | Quantifies main component by reverse-phase HPLC with UV detection at 254 nm, using external standard calibration. |
| Sodium content | ICP-OES | Measures Na+ concentration after acid digestion and dilution via plasma emission spectroscopy. |
| Total inorganic sulfate | Ion Chromatography | Separates and quantifies SO4(2-) anions using suppressed conductivity detection. |
| Residual solvents (e.g., methanol, water) | GC-FID | Detects volatile organic solvents by gas chromatography with flame ionization detection. |
| Heavy metals (Pb, Cd, Hg, As) | ICP-MS | Quantifies trace heavy metals after microwave-assisted acid digestion using mass spectrometric detection. |
| Chloride impurity | Potentiometric titration | Determines Cl- concentration using silver nitrate titrant and silver/silver chloride indicator electrode. |
| pH of aqueous solution | pH meter measurement | Measures hydrogen ion activity in a 1% w/v aqueous suspension at 25 C. |
| Loss on drying (LOD) | Gravimetric thermogravimetry | Determines volatile content by weight loss after drying at 105 C for 2 h under vacuum. |
| Appearance (color and physical form) | Visual inspection | Assesses homogeneity, color (white to off-white), and absence of visible particulates or caking. |
| Particle size distribution | Laser diffraction | Measures particle size range (D10, D50, D90) in dispersed aqueous suspension using light scattering. |
| Water content | Karl Fischer titration | Quantifies total water by coulometric or volumetric titration with iodine-based reagent. |
| Related substances (degradation products) | HPLC-DAD | Identifies and quantifies structural analogs and oxidation by-products using diode array detection. |
