Manufacturing Quality Control of Tetramethylammonium fluoride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (TMAF content) | Acid-base titration with standardized HCl | Quantifies TMAF by back-titration after reaction with excess standardized hydrochloric acid. |
| Water content | Karl Fischer titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine-methanol medium. |
| Chloride impurity | Ion chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate impurity | Ion chromatography (IC) | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Heavy metals (Pb, Cd, Ni, etc.) | ICP-OES | Multi-element quantification based on element-specific atomic emission intensities after plasma atomization. |
| Iron content | AAS (Flame) | Measures iron absorption of characteristic wavelength light after nebulization and atomization in air-acetylene flame. |
| pH of aqueous solution | Potentiometric pH measurement | Determines hydrogen ion activity using calibrated glass electrode in standardized 1% w/v aqueous solution. |
| Residue on ignition | Gravimetric analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing at 500-600 C. |
| Organic impurities | GC-FID | Separates and quantifies volatile organic impurities using capillary column and flame ionization detection. |
| Particle size distribution | Laser diffraction | Measures particle size based on angular dependence of laser light scattering in dispersed sample. |
| Bulk density | Gravimetric volumetric method | Calculates mass per unit volume using standardized funnel and graduated cylinder under controlled tapping. |
| Microbial contamination | Membrane filtration assay | Detects viable aerobic microorganisms by filtration, membrane transfer to agar, and colony enumeration after incubation. |
