| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies active B(OH)2 groups via back-titration after reaction with standardized acid. |
| Moisture Content | Karl Fischer Titration | Measures water content electrochemically by iodine oxidation of sulfur dioxide in methanol. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration and weight measurement. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metals using plasma-excited atomic emission spectra. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects Cl- ions by silver nitrate titration monitored with silver indicator electrode. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates SO4(2-) as BaSO4 and determines mass after filtration and drying. |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Measures Fe concentration by absorption of specific wavelength light by ground-state Fe atoms. |
| pH of Aqueous Solution | pH Meter Measurement | Determines hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution based on angular variation of scattered laser light intensity. |
| Organic Volatile Impurities | GC-FID | Separates and quantifies residual solvents using gas chromatography with flame ionization detection. |
| Boron Content | Alkali Fusion followed by Acid-Base Titration | Converts boron to boric acid via NaOH fusion, then titrates liberated acid. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely settled powder under standardized conditions. |
