Overview

EN 16761-2:2015 - "Automotive fuels - Determination of methanol in automotive ethanol (E85) fuel by gas chromatography - Part 2: Method using heart cut technique" is a CEN European Standard that specifies a capillary gas chromatography (GC) procedure, using a heart‑cut technique and flame ionization detection (FID), for measuring methanol in E85 automotive fuel. The method is applicable primarily to fuels containing about 0.5 % (V/V) to about 1.5 % (V/V) methanol. The standard includes requirements for sampling, apparatus, calibration, chromatographic performance and safety considerations.

Key topics and technical requirements

  • Analytical principle: Heart‑cut GC using a non‑polar pre‑column and a polar analytical column to transfer (cut) the methanol-containing fraction for separation from ethanol and hydrocarbons before FID detection.
  • Columns & configuration: Typical set includes a PDMS pre‑column (e.g. 30 m × 0.53 mm × 0.88 µm), a polar analytical column (e.g. 10 m × 0.53 mm × 10 µm), and a short monitor column. A Pressure Control Module (PCM) and switching valve control the heart cut.
  • Calibration: External single‑point calibration (recommended in duplicate) using an E85 matrix reference solution; optional linearity check with multi‑level dilutions if linearity is in doubt. Response factor calculated from calibration peak area.
  • Recommended operating examples: oven program (100 °C for 5 min, then 25 °C/min to 250 °C), injector ≈200 °C, detector ≈250 °C, injection volume ~0.5 µL, split ~100:1, valve switching times tuned (example: valve on at ~1.8 min, off at ~2.02 min).
  • Performance checks: minimum chromatographic resolution for methanol/ethanol ≥ 3.0; peak skewness (B/A) between 1 and 4.
  • Sample handling & density: sampling per EN ISO 3170/3171; density at 15 °C to be measured (EN ISO 3675/3838/12185).
  • Safety: method may involve hazardous gases and solvents; users must establish appropriate safety practices.

Applications and users

  • Quality control laboratories in fuel producers and distributors verifying methanol content in E85 blends.
  • Regulatory and compliance testing to check E85 against fuel quality and EU emissions‑related requirements.
  • Third‑party testing labs supporting vehicle manufacturers, fuel retailers and certification bodies.
  • Research groups developing or validating GC methods for oxygenated fuels.

Practical value: the heart‑cut technique improves selectivity for methanol in complex ethanol‑rich matrices (E85), making results less affected by impurities or high‑boiling components.

The article discusses the European Standard EN 16761-2:2016, which outlines a method for determining the methanol content in automotive ethanol (E85) fuel using capillary gas chromatography with heart cutting and flame ionisation detection. The standard is specifically designed for fuels with a methanol content ranging from approximately 0.5% to 1.6% (V/V). While the method can be used for a broader range of methanol content (0.1% to 2.2% V/V), its precision has not been established for the entire range.
