Manufacturing Quality Control of Ethyltriphenylphosphonium iodide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent, measuring endpoint coulometrically or volumetrically. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents by gas chromatography with flame ionization detection using a polar capillary column. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element determination after acid digestion, based on atomic emission intensity at characteristic wavelengths in an inductively coupled plasma. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection, using sodium carbonate/bicarbonate eluent. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against a white background under controlled lighting. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying a sample at 105 C for 2 hours under vacuum or nitrogen purge. |
| Residue on Ignition | Sulfated Ash Method | Weighing residue remaining after charring and incinerating at 600 C in a platinum crucible with sulfuric acid pretreatment. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, corrected for concentration and path length. |
| pH of Aqueous Suspension | pH Meter | Determination of hydrogen ion activity in a 1% w/v suspension in purified water using a calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in a dispersed slurry. |
