| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID or GC-MS | Quantitative determination by comparing peak area of analyte to that of a reference standard using gas chromatography with flame ionization or mass spectrometric detection. |
| Related Substances | GC-MS or HPLC-UV | Separation and identification of impurities based on retention time and spectral match, followed by area normalization or external standard quantification. |
| Residual Solvents | GC-FID | Volatile organic solvents are separated by gas chromatography and quantified against certified standards using flame ionization detection. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration where iodine reacts stoichiometrically with water in a controlled electrochemical or chemical system. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on an ion-exchange column followed by conductivity detection and quantification against calibration standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection and quantification of trace metals after acid digestion, based on mass-to-charge ratio and isotopic abundance. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue remaining after high-temperature ashing at 600-800 C. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary tube method per USP/Ph. Eur. guidelines. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the sample against defined standards under controlled lighting conditions. |
| Acidity/Alkalinity | Acid-Base Titration | Titration with standardized NaOH or HCl solution to determine free acidic or basic impurities based on neutralization endpoint. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size by analyzing angular variation in laser light scattering intensity from a dispersed sample. |
| Bulk Density | Tap Density Tester | Determination of mass per unit volume after controlled mechanical tapping of a known mass in a graduated cylinder. |
