Manufacturing Quality Control of Copper (I) diphenylphosphinate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Cu content) | ICP-OES | Quantifies copper concentration via atomic emission intensity of excited Cu atoms in plasma. |
| Assay (P content) | ICP-OES | Quantifies phosphorus concentration via atomic emission intensity of excited P atoms in plasma. |
| Assay (C/H/N content) | Elemental Analyzer (CHNS/O) | Determines carbon, hydrogen, and nitrogen mass percentages by high-temperature combustion and gas chromatographic detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Measures trace heavy metal concentrations using mass-to-charge ratio detection of ionized atoms. |
| Moisture Content | Karl Fischer Titration | Determines water content by stoichiometric reaction between water and iodine in a controlled electrochemical titration. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities as weight remaining after high-temperature ashing. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions based on anion exchange retention and conductivity detection. |
| Organic Volatile Impurities | GC-FID | Detects and quantifies residual solvents or volatile organics using gas chromatographic separation and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Determines particle size distribution by analyzing angular dependence of scattered laser light. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume of powder after standardized mechanical tapping. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting and white background. |
