Manufacturing Quality Control of Octaethylene glycol
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent container and observe its color, clarity, and presence of suspended particles or precipitates under natural light or standard lighting. Octaethylene glycol should be a colorless, clear, viscous liquid. |
| Color Intensity | Platinum-Cobalt Colorimetric Method (GB/T 3143 or APHA) | Compare the sample with standard platinum-cobalt solutions to determine its color value, which assesses product purity and degree of oxidation. Lower values indicate higher purity. |
| Purity / Main Component Content | Gas Chromatography (GC) | After derivatization (e.g., silylation), separate components using gas chromatography and quantify octaethylene glycol content via a flame ionization detector (FID). |
| Moisture Content | Karl Fischer Titration | Utilize the quantitative reaction of iodine, sulfur dioxide, and water in methanol; determine moisture content by coulometric or volumetric titration. Suitable for trace water detection. |
| pH Value | pH Meter Method | Dissolve octaethylene glycol in water (typically as a 1%–5% aqueous solution) and measure acidity or alkalinity using a calibrated pH meter to determine if it is neutral. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | Add sulfuric acid to a known quantity of sample, char, then ignite at high temperature until constant weight. Weigh the residue and calculate the percentage to reflect inorganic impurity content. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine concentrations of heavy metals such as lead, cadmium, and mercury using atomic absorption spectroscopy or inductively coupled plasma mass spectrometry (ICP-MS) to ensure compliance with safety standards. |
| Residual Ethylene Oxide / Ethylene Glycol | Gas Chromatography (GC) | Detect residual small-molecule impurities such as ethylene oxide and ethylene glycol—byproducts from synthesis—using headspace or direct injection GC. |
| Molecular Weight Distribution | Gel Permeation Chromatography (GPC/SEC) | Separate components by molecular weight using a gel chromatography column and analyze molecular weight and distribution with a refractive index detector to evaluate polymer uniformity. |
