Manufacturing Quality Control of 13688-56-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area against calibrated standard; uses internal or external standard for concentration calculation. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual methacrylic acid) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry (430 nm) | Compares sample color to APHA platinum-cobalt standards; spectrophotometric version measures absorbance at 430 nm in 10-mm cell. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measures oscillation period of a U-shaped tube filled with sample; correlates to density via calibration with reference fluids. |
| Refractive Index at 20 C | Abbe Refractometer | Determines refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known mass of sample under controlled conditions and weighs non-volatile residue after drying. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions using ion-exchange column and conductivity detection; or titrates with silver nitrate using chloride-selective electrode. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in argon plasma; quantifies metal emission lines at characteristic wavelengths. |
| Residual Solvents (e.g., Hexane, Toluene) | Headspace Gas Chromatography (HS-GC) | Equilibrates sample in sealed vial, injects vapor phase into GC column for separation and FID detection. |
| Viscosity at 25 C | Rotational Viscometer | Measures torque required to rotate a spindle at fixed speed in sample; calculates dynamic viscosity from shear stress and shear rate. |
| Peroxide Value | Iodometric Titration | Peroxides oxidize iodide to iodine under acidic conditions; liberated iodine is titrated with standardized sodium thiosulfate. |
