Overview
EN 13320:2002 is a European Standard developed by CEN that defines a precise test method for determining the content of free ethylene oxide (EO) in surface active agents, specifically polyglycols, ethoxylates of alcohols and alkylphenols, and fatty acid polyglycol esters. The standard covers the quantitative trace determination of free ethylene oxide within the concentration range of 1 mg/kg to 100 mg/kg using gas chromatography with head-space sampling.
This method is vital for ensuring product safety and compliance in the manufacture and quality control of surfactants that include ethoxylated compounds, where residual free ethylene oxide can pose health and environmental hazards.
Key Topics
Scope and Applicability
Specifies a gas chromatographic method to detect and quantify free ethylene oxide in ethoxylates and related compounds essential for controlling residual EO in industrial products.Analytical Principle
Analysis is conducted by head-space gas chromatography (GC) with flame ionization detection (FID). Free ethylene oxide in the sample is measured using the standard addition method for accuracy.Reagents and Equipment
Requires high purity water, ethylene oxide standards, N,N-dimethylformamide, and other analytical-grade reagents. Essential equipment includes a capillary gas chromatograph equipped with a head-space sampler and a fused silica column coated with crosslinked dimethylpolysiloxane.Sample Preparation
Laboratory samples must be handled following ISO 607 guidance. Samples can be liquids, pastes, or solids that may require gentle warming to liquefy without exceeding 50 °C to avoid decomposition of EO.Calibration and Testing Procedures
Employs carefully prepared ethylene oxide standard solutions and calibration solutions for method validation. Test samples are prepared with and without standard additions in vials sealed for head-space GC analysis.Calculation and Expression of Results
The EO content (micrograms per gram) is computed based on chromatographic peak areas adjusted by sample weight and calibration factors. Results are averaged for reproducibility.Precision and Reliability
Includes repeatability and reproducibility limits validated by interlaboratory ring tests to assure method consistency across labs.Test Reporting Requirements
Mandates detailed reporting on sample identification, test conditions, GC settings if altered, observed EO levels, and any deviations or issues encountered during testing.
Applications
Surfactant Quality Control
Essential for manufacturers of surface active agents to monitor residual free ethylene oxide levels in products such as detergents, emulsifiers, and wetting agents.Safety Compliance
Helps ensure compliance with regulatory limits on ethylene oxide residues, minimizing health risks associated with EO exposure during product use or handling.Research and Development
Supports R&D activities aimed at optimizing ethoxylation processes and reducing residual EO in new or improved surfactant formulations.Environmental Monitoring
Enables monitoring of EO emissions and residues in environmental samples related to industrial surfactant production facilities.
