Manufacturing Quality Control of propyl methanesulphonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities; endpoint detected potentiometrically or with phenolphthalein. |
| Color | Visual Comparison to APHA Scale | Compares sample color in solution to platinum-cobalt standard solutions under controlled lighting. |
| Density | Digital Density Meter | Determines density from oscillation period of U-tube filled with sample at controlled temperature. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at specified wavelength and temperature. |
| Residue on Ignition | Gravimetric Analysis | Weighs non-volatile residue remaining after high-temperature ashing of sample. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals after acid digestion by atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using conductivity detection after anion exchange separation. |
| Residual Solvents (e.g., methanol, acetone) | Headspace GC-FID | Detects volatile solvents by gas-phase equilibrium extraction followed by chromatographic separation. |
| Appearance | Visual Inspection | Assesses clarity and presence of particulates or phase separation in undiluted sample under ambient light. |
| Boiling Range | Distillation (ASTM D1078) | Determines temperature interval over which 90% of sample distills under controlled vacuum and heating rate. |
