Manufacturing Quality Control of 12025-34-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Ge Content | ICP-OES | Quantifies germanium by measuring intensity of characteristic atomic emission lines after plasma atomization and excitation. |
| S Content | Combustion IC | Determines sulfur by high-temperature combustion to SO2, followed by ion chromatographic separation and conductivity detection. |
| Impurity Metals (Fe, Cu, Pb, Ni, etc.) | ICP-MS | Measures trace metal impurities via mass spectrometric detection of elemental ions after plasma ionization. |
| Moisture Content | Karl Fischer Titration | Determines water content by stoichiometric reaction between water and iodine in a methanol-based reagent. |
| Loss on Ignition (LOI) | Thermogravimetric Analysis | Measures mass loss upon controlled heating to assess volatile content, adsorbed water, and organic residues. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size by measuring angular variation in intensity of laser light scattered by suspended particles. |
| Bulk Density | ASTM D1895 | Determines mass per unit volume of freely settled powder using a calibrated cylinder and balance. |
| pH of Aqueous Slurry | Potentiometric pH Measurement | Measures hydrogen ion activity in a water slurry using a calibrated glass electrode system. |
| Chloride Ion | Ion Chromatography | Separates and quantifies chloride anions via ion-exchange chromatography with suppressed conductivity detection. |
| Residue on Sieve (e.g., 45 um) | Dry Sieving | Assesses coarse particle contamination by mechanical sieving and gravimetric analysis of retained material. |
| Organic Volatiles | Headspace GC-MS | Detects residual solvents or organics by thermal equilibration in headspace vial followed by gas chromatographic separation and mass spectrometric detection. |
| Crystal Phase | X-ray Diffraction (XRD) | Identifies crystalline phases by analyzing diffraction angles and intensities of X-rays scattered by lattice planes. |
