Manufacturing Quality Control of 15963-40-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on mass spectral fragmentation patterns and retention behavior. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Measures water via electrochemical iodine generation and stoichiometric reaction with sample water. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines inorganic residue after high-temperature ashing of sample at 700-800 C. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralizes free carboxylic acid groups; endpoint detected potentiometrically or with phenolphthalein. |
| Color | Visual Comparison Against Platinum-Cobalt Standard | Compares sample color to standardized Pt-Co scale in a Nessler tube under controlled lighting. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Measures sample density from resonant frequency shift of vibrating U-shaped glass tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Determines refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride anions using ion-exchange column and suppressed conductivity detection. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in argon plasma; detects characteristic emission lines of heavy metals. |
| Non-Volatile Residue | Evaporation and Gravimetric Weighing | Dries sample under controlled heat and vacuum, then weighs residual non-volatile matter. |
| Optical Rotation | Polarimetry | Measures angular rotation of plane-polarized light induced by chiral centers in the compound. |
