| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID or HPLC-UV | Quantitative determination using calibrated chromatographic separation and detection of the main peak area relative to reference standard. |
| Residual Solvents | GC-FID with headspace sampling | Volatile organic impurities are separated by gas chromatography and quantified against certified standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion, based on element-specific atomic emission intensities. |
| Residual Boron | ICP-OES or ICP-MS | Quantification of total boron content post-acid digestion via elemental emission or mass spectrometry. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity under controlled lighting against established reference standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Residual Palladium | ICP-MS | Ultra-trace detection of palladium after microwave digestion, based on isotope-specific mass-to-charge ratio. |
| Organoborane By-products | HPLC-ELSD | Separation followed by evaporation light-scattering detection for non-UV-absorbing boron-containing impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to derive volume-based particle size distribution. |
