Manufacturing Quality Control of METHYL VINYL ETHER/MALEIC ACID COPOLYMER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode-array detection; relative retention times and UV spectra support structural assignment. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using mass spectrometry for high sensitivity and selectivity. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with conductivity detection; chloride is quantified via calibration curve. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH solution in ethanol/isopropanol mixture; endpoint detected potentiometrically or by phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Ignition of sample at 700-800 C followed by weighing of non-volatile inorganic residue; measures total inorganic ash content. |
| Appearance | Visual Inspection | Assessment of color and clarity of a solution in specified solvent (e.g., methanol) against standard references under controlled lighting. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light by chiral compound in solution; correlates with enantiomeric purity and identity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination using calibrated glass electrode in a saturated aqueous suspension or dilute solution at specified temperature and concentration. |
| Bulk Density | Tap Density Measurement | Mass per unit volume after controlled tapping of a graduated cylinder containing the powder; reflects flowability and handling characteristics. |
