Manufacturing Quality Control of ETHYLENE GLYCOL BIS(3-MERCAPTOPROPIONATE)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine consumption in pyridine-methanol solvent. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid groups by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Thiol Content | Iodometric Titration | Quantifies -SH groups by reaction with excess iodine, followed by back-titration of unreacted iodine with sodium thiosulfate. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Evaluates yellowness by comparing sample absorbance at 430 nm to APHA color scale standards. |
| Density at 25 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement with sodium D-line (589 nm). |
| Residue on Ignition | Gravimetric Analysis after Ashing | Measures non-volatile inorganic impurities by weight difference before and after high-temperature combustion. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at element-specific wavelengths after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions via conductivity detection (IC) or silver nitrate titration with potentiometric endpoint. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents by equilibrium partitioning into headspace followed by GC-FID analysis. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of particulates or phase separation under controlled lighting conditions. |
