Manufacturing Quality Control of Ethyl methanesulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated at 700-800 C to constant weight; residue mass expressed as percentage of original sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead-specific hollow cathode lamp and air-acetylene flame. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column followed by quantitative detection via suppressed conductivity. |
| Sulfate Impurity | Barium Chloride Turbidimetry | Precipitation of sulfate as BaSO4 in acidic medium; turbidity measured spectrophotometrically at 420 nm. |
| Color | Visual Comparison Against APHA Scale | Sample color assessed in a Nessler tube by direct visual comparison to platinum-cobalt standard solutions. |
| Density | Digital Density Meter (Oscillating U-tube) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index | Abbe Refractometer | Determination of refractive index at 20 C using sodium D-line light source and critical angle measurement. |
| Ethanol Impurity | Gas Chromatography (GC) with FID | Separation and quantification of residual ethanol using polar capillary column and internal standard calibration. |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Mass loss measured under nitrogen purge from 25 C to 200 C at fixed heating rate; residue reported as % mass remaining. |
