Manufacturing Quality Control of PENTAETHYLENE GLYCOL
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent container and observe its color and clarity under natural light. It should be a colorless, transparent liquid with no visible impurities. |
| Color Intensity | Platinum-Cobalt Colorimetric Method (GB/T 3143 or APHA) | Compare sample color against standard platinum-cobalt solutions to determine color depth, used to assess purity and degree of oxidation. |
| Assay | Gas Chromatography (GC) | After derivatization (e.g., silylation), inject sample and use FID detector to separate and quantify the peak area of pentaethylene glycol; calculate concentration using external or internal standard method. |
| High-Performance Liquid Chromatography (HPLC) | Use refractive index detector (RID) or evaporative light scattering detector (ELSD) with a hydrophilic column (e.g., NH₂ column) for separation and quantification. | |
| Water Content | Karl Fischer Titration | Determine water content precisely by coulometric or volumetric titration based on the reaction of iodine and sulfur dioxide with water in a pyridine/methanol system. |
| pH Value | pH Meter Method | Prepare an aqueous solution of pentaethylene glycol (e.g., 5%–10%), then measure acidity or alkalinity using a calibrated pH meter. The value typically falls within 5.0–7.5. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | Add sulfuric acid to the sample, char, then ignite at high temperature until constant weight. Weigh the residue and calculate the percentage to indicate inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, measure concentrations of heavy metal elements such as lead, arsenic, cadmium, and mercury to ensure compliance with pharmacopeial or electronic-grade material limits. |
| Ethylene Glycol and Oligomer Impurities | Gas Chromatography (GC) or HPLC | Separate and detect impurity peaks including mono-, di-, tri-, and tetraethylene glycols to evaluate product purity and control of synthesis by-products. |
| Refractive Index (n²⁰D) | Refractometry | Measure the refractive index of the sample at 20°C using sodium light (589 nm), useful for identification and purity assessment. |
| Viscosity | Rotational Viscometer Method | Measure dynamic or kinematic viscosity at a specified temperature (e.g., 25°C) using a rotational viscometer to characterize fluid behavior. |
