Manufacturing Quality Control of Tetraethylammonium fluoride trihydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (TEFA content) | Acid-base titration with standardized HCl | Quantifies TEFA by acid hydrolysis followed by back-titration of excess acid with standardized base. |
| Water content | Karl Fischer titration | Measures total water (including hydrate water) via iodometric reaction with Karl Fischer reagent. |
| Fluoride ion content | Ion-selective electrode (ISE) potentiometry | Determines free F- concentration using fluoride-specific membrane electrode and calibration curve. |
| Chloride impurity | Ion chromatography (IC) | Separates and quantifies Cl- anions based on retention time and conductivity detection. |
| Sulfate impurity | Ion chromatography (IC) | Separates and quantifies SO42- anions using suppressed conductivity detection. |
| Heavy metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification after acid digestion using plasma excitation and wavelength-specific emission detection. |
| Residue on ignition | Gravimetric analysis | Measures non-volatile inorganic residue after high-temperature ashing at 550-600 C. |
| pH of aqueous solution | pH meter measurement | Determines hydrogen ion activity in a defined aqueous suspension or solution using calibrated pH electrode. |
| Appearance and color | Visual inspection against standard | Assesses physical state, homogeneity, and color deviation from reference white crystalline standard. |
| Particle size distribution | Laser diffraction | Measures particle size range and distribution by analyzing angular scattering pattern of laser beam. |
| Organic impurities | HPLC-UV | Separates and detects residual organic solvents or degradation products using reversed-phase column and UV detection. |
| Loss on drying | Thermogravimetric analysis (TGA) | Quantifies mass loss upon controlled heating to determine volatile content including hydration water. |
