Manufacturing Quality Control of 13688-55-6
| 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. |
| Moisture Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Number | Acid-Base Titration (NaOH in isopropanol) | Neutralization of acidic impurities (e.g., residual acrylic acid) with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped glass tube filled with the sample. |
| Refractive Index at 20 C | Digital Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA measurement | Comparison of sample color to platinum-cobalt standard solutions using spectrophotometric absorbance at 430 nm. |
| Residue on Evaporation | Gravimetric Analysis (Hot Plate Evaporation) | Evaporation of a known mass of sample under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride ions on an anion-exchange column and quantification via suppressed conductivity detection. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in high-temperature plasma; detection based on element-specific emission wavelengths. |
| Vinyl Content | 1H Nuclear Magnetic Resonance (1H NMR) Spectroscopy | Quantification of vinyl protons (CH2=CH-) relative to reference signals (e.g., TMS or internal standard) in deuterated chloroform. |
| Hydrolyzable Chloride | Potentiometric Titration with AgNO3 | Precipitation titration where silver nitrate reacts with chloride ions; endpoint detected by silver ion-selective electrode potential change. |
| Total Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of volatile organic impurities using capillary GC coupled to electron ionization mass spectrometer. |
